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 mode¹
“11xxx”=Enable sleep mode²
“1x100”=Force enter sleep2³
“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 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 90 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.

Wakeup
Manual enter sleep1 mode, set “1” will enter sleep2 and this bit will be reset to “0”
Manual wake up from sleep mode, set “1” will enter wakeup and this bit will be
reset to “0”
