Usage

Operation_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

automatically.)

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.
