Usage 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

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 200 ms 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 200 ms 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 30 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.

Sleep mode enable/disable

0 = Disable

1 = Enable (Default)

Slp2au

Automatic enter sleep2 mode enable/disable

0 = Disable

1 = Enable (Default)

Slp2mu

Manual enter sleep2 mode, set “1” will enter sleep2 and this bit will be reset to “0”

Slp1mu

Manual enter sleep1 mode, set “1” will enter sleep2 and this bit will be reset to “0”

Notes

Wakeup

Manual wake up from sleep mode, set “1” will enter wakeup and this bit will be reset

to “0”
