Register 0x05 allows the user to change the operation of the sensor. Shown below are the bits, their
default values, and optional values.
Operation_Mode[4:0]
“0x0xx” = Disable sleep mode
“100xx” = Enable sleep mode¹
“110xx” = Enable sleep mode²
“1x010” = Force enter sleep1³
“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 78 ms 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.
2. Enable sleep mode full function, that is 3 modes will be used, normal mode, sleep1 mode and sleep2
mode. After 78 ms 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 60 sec ±40% 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.
Mode
Sampling rate @6600 frame/sec Active duty cycle @6600 frame/sec
Sleep1
45/sec
22.7%
Sleep2
3/sec
1.6%
Note that these values have ±40% range above list. (ex: 45/sec -> 27/sec ~ 63/sec)
3. Only one of slp1mu_enh and wakeup bit 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.
