Register 0x1A allows the user to change the operation of the mouse sensor. Shown below are the bits,
their default values, and optional values.
Operation_Mode2[2:0]
“0xx” = Disable sleep mode
“110” = Force enter sleep
“101” = Force wakeup from sleep mode
Notes:
1. After 1 sec not moving during normal mode, the mouse sensor will enter sleep mode, and keep on
sleep mode until moving is detected or wakeup is asserted.
2. Only one of these two bits Slpmu_enh and Wakeup can be set to 1 at the one time, and the other
one has to be set to 0. Note that these bits are self-clear.
