Reserved[3:0] is a value between 0x0 and 0xF, it can’t be used to verify that the serial communications. Motion_Status Bit 7 6 5 4 3 2 1 0 Field Motion Usage Reserved[1:0] DYOVFDXOVF RES[2:0] Motion_Status register allows the user to determine if motion has occurred since the last time it was read. If so, then the user should read Delta_X and Delta_Y registers to get the accumulated motion. It also tells if the motion buffers have overflowed since the last reading. The current resolution is also shown. Reading this register freezes the Delta_X and Delta_Y register values. Read this register before reading the Delta_X and Delta_Y registers. If Delta_X and Delta_Y are not read before the motion register is read a second time, the data in Delta_X and Delta_Y will be lost. Notes Field Name Motion Description Motion since last report 0 = No motion (Default) 1 = Motion occurred, data ready for reading in Delta_X and Delta_Y registers Reserved[1:0] Reserved for future use DYOVF Motion Delta Y overflow, ΔY buffer has overflowed since last report 0 = No overflow (Default) 1 = Overflow has occurred Motion Delta X overflow, ΔX buffer has overflowed since last report 0 = No overflow (Default) 1 = Overflow has occurred Resolution in counts per inch 000 = 400 001 = 500 010 = 600 011 = 800 100 = 1000 (Default) 101 = 1200 110 = 1600 DXOVF RES[2:0] All rights strictly reserved any portion in this paper shall not be reproduced, copied or transformed to any other forms without permission. 5

0x05 Operation_Mode Bit 7 Field LEDsht_enh Usage 6 5 4 3 2 1 0 Slp_enh Slp2_enh0 1 Slp2mu Slp1mu WakeupOperation_Mode register allows the user to change the operation of the mouse sensor. Shown below are the bits, their default values, and optional values. Operation_Mode[4:0] “0xxxx” = Disable sleep mode “10xxx” = Enable sleep mode1 “11xxx” = Enable sleep mode2 “11100” = Force enter sleep23 “1x010” = Force enter sleep13 (If Slp2_enh is set, the mouse sensor still enter the sleep2 automatically.) “1x001” = Force wakeup from sleep mode3 Notes: 1. Enable sleep mode, but disable automatic entering sleep2 mode, that is, only 2 modes will be used, normal mode and sleep1 mode. After 256 ms (±20%) not moving during normal mode, the mouse sensor will enter sleep1 mode, and keep on sleep1 mode until moving is detected or wakeup is asserted. Note that the entering time depends on the setting of Enter_Time register. 2. Enable sleep mode full function, which is 3 modes will be used, normal mode, sleep1 mode and sleep2 mode. After 256 ms (±20%) not moving during normal mode, the mouse sensor will enter sleep1 mode, and keep on sleep1 mode until moving is detected or wakeup is asserted. And after 61 sec (±20%) not moving during sleep1 mode, the mouse sensor will enter sleep2 mode, and keep on sleep2 mode until detect moving or force wakeup to normal mode. Note that the entering time depends on the setting of Enter_Time register. 3. Only one of these three bits slp2mu_enh, slp1mu_enh, and wakeup can be set to 1 at the same time, others have to be set to 0. After a period of time, the bit, which was set to 1, will be reset to 0 by internal signal. 4. The user can clear Slp_enh/Slp2_enh bit to make the mouse sensor enter normal mode. If the user clears Slp_enh/Slp2_enh bit during normal mode, the mouse sensor will keep its status. If the user clears Slp_enh/Slp2_enh bit during sleep mode, the mouse sensor will enter normal mode after it detect any movement or the user sets Wakeup bit.

Shown below are the bits, their default values, and optional values. If MotSwk bit is clear, the MOTSWK pin is level-sensitive. The pin level remains low when motion has occurred; in other words, Delta_X and Delta_Y registers has data. The mouse controller can read Motion_Status register, Delta_X register, then Delta_Y register sequentially. After the mouse controller reads all data, Delta_X and Delta_Y are both zero, the pin level will be high (see Section 7). If MotSwk bit is set, the MOTSWK pin is edge-sensitive. The pin will send a pulse and trigger the mouse controller when motion has occurred during the sleep mode. The mouse controller can read Motion_Status register, Delta_X register, then Delta_Y register sequentially (see Section 7).

6. Serial Interface

The synchronous serial port is used to set and read parameters in the mouse sensor. SCLK: The serial clock line. It is always generated by the mouse controller. SDIO: The serial data line is used to write and read data. 6.1 Transmission Protocol The transmission protocol is a two-wire link, half duplex protocol between the micro-controller and the mouse sensor. All data changes on SDIO are initiated by the falling edge on SCLK. The mouse controller always initiates communication; the mouse sensor never initiates data transfers. The transmission protocol consists of the two operation modes: - Write Operation. - Read Operation. Both of the two operation modes consist of two bytes. The first byte contains the address (seven bits) and has a bit 7 as its MSB to indicate data direction. The second byte contains the data. FIRST BYTER/W(1 BIT)ADDRESS (7 BIT)SECOND BYTEDATA (8 BIT)MSBLSBMSBLSB Figure 7. Transmission Protocol 6.1.1 Write Operation A write operation, which means that data is going from the mouse controller to the mouse sensor, is always initiated by the mouse controller and consists of two bytes. The first byte contains the address (seven bits) and has a “1” as its MSB to indicate data direction. The second byte contains the data. The transfer is synchronized by SCLK. The mouse controller changes SDIO on falling edges of SCLK. The mouse sensor reads SDIO on rising edges of SCLK.

6.1.2 Read Operation

A read operation, which means that data is going from the mouse sensor to the mouse controller, is always initiated by the mouse controller and consists of two bytes. The first byte contains the address, is written by the mouse controller, and has a “0” as its MSB to indicate data direction. The second byte contains the data and is driven by the mouse sensor. The transfer is synchronized by SCLK. SDIO is changed on falling edges of SCLK and read on every rising edge of SCLK. The mouse controller must go to a high Z state after the last address data bit. The mouse sensor will go to the high Z state after the last data bit.

Read Operation 6.2 Re-Synchronous Serial Interface If the mouse controller and the mouse sensor get out of synchronization, then the data either written or read from the registers will be incorrect. In such a case, an easy way to solve this condition is to toggle the SCLK line from high to low for least tRESYNC, and then MUST toggle it from low to high to wait at least tSIWTT to reach re-synchronous the serial port. This method is called by “watchdog timer timeout”. The mouse sensor will reset the serial port without resetting the registers and be prepared for the beginning of a new transmission. tSIWTTSCLKtRESYNC1u s, minSDIO123456710111213141516Hi-ZADDRESS (R/W)_DATA Figure 10. Re-synchronous Serial Interface Using Watchdog Timer Timeout Note that this function is disabled when the mouse sensor is in the power down mode. If the user uses this function during the power down mode, it will get out of synchronization. The mouse sensor and the mouse controller also might get out of synchronization due to following conditions.

Power On Problem - The problem occurs if the mouse sensor powers up before the mouse controller sets the SCLK and SDIO lines to be output. The mouse sensor and the mouse controller might get out of synchronization due to power on problem. An easy way to solve this is to use “watchdog timer timeout”. ESD Events - The mouse sensor and the mouse controller might get out of synchronization due to ESD events. An easy way to solve this is to use “watchdog timer timeout”. z

6.3 Collision Detection on SDIO The only time that the mouse sensor drives the SDIO line is during a READ operation. To avoid data collisions, the mouse controller should release SDIO before the falling edge of SCLK after the last address bit. The mouse sensor begins to drive SDIO after the next falling edge of SCLK. The mouse sensor releases SDIO of the rising SCLK edge after the last data bit. The mouse controller can begin driving SDIO any time after that. In order to maintain low power consumption in normal operation or when the PD pin is pulled high, the mouse controller should not leave SDIO floating until the next transmission (although that will not cause any communication difficulties). 6.4 Power Down Mode The mouse sensor can be placed in a power-down mode by setting PD_enh bit in the Configuration register via a serial port write operation. After setting the Configuration register, wait at most 2 frames times. To get the chip out of the power down mode, clear PD_enh bit in the Configuration register via a serial port write operation. In the power down mode, the serial interface watchdog timer (see Section 6.2) is not available. But, the serial interface still can read/write normally. For an accurate report after leave the power down mode, wait about 3ms before the mouse controller is able to issue any write/read operation to the mouse sensor.

7. MOTSWK function 7.1 Motion function To use Motion function, the MotSwk bit in the Configuration register must be set to zero. Motion is used to monitor if the mouse sensor has finished sending X-Y movement data to the mouse controller. If all movement data are not read, MOTSWK pin level will remain low. After the mouse controller reads all movement data from the mouse sensor, the mouse sensor will set MOTSWK pin level to high. Note “A”MotionNote “A”Note “B”Note “A”: Delta_X / Delta_Y are equal to 0.Note “B”: Delta_X / Delta_Y are not equal to 0. Figure 12. Motion function 7.2 SWKINT function To use SWKINT function, the MotSwk bit in the Configuration register must be set to one. SWKINT works when the mouse sensor is in the sleep mode and the mouse controller is also in the sleep mode. If the mouse sensor detects any motion occurrence at this moment, the mouse sensor will wake the mouse controller up promptly via MOTSWK pin. The mouse sensor will trigger the mouse controller at the rising/falling edge of MOTSWK pin. SWKINTtSWKINT Figure 13.
