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]
“0xxxx”=Disable sleep mode
“10xxx”=Enable sleep mode
1
“11xxx”=Enable sleep mode
2
“1x100”=Force enter sleep2
3
“1x010”=Force enter sleep1
3
“1x001”=Force wakeup from sleep mode

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 1 sec not moving during normal mode, the chip 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 1 sec not moving during normal mode, chip will enter sleep1 mode, and keep on sleep1
mode until moving is detected or wakeup is asserted.
And after 60 sec not moving during sleep1 mode, the chip will enter sleep2 mode, and keep on sleep2
mode until detect moving or force wakeup to normal mode.

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 bits, which was set to 1, will be reset to 0 by
internal signal.
