Slp_enl
Register 0x00 allows the user to change the operation of the mouse sensor. Shown below are the bits,
their default values, and optional values.
If Slp_enl = 0, 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.
