3. Only one of these three bits slp2mu, slp1mu, 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_en/Slp2_en bit to make the mouse sensor enter normal mode. If the
user clears Slp_en/Slp2_en bit during normal mode, the mouse sensor will keep its status. If the
user clears Slp_en/Slp2_en bit during sleep mode, the mouse sensor will enter normal mode
after it detect any movement or the user sets Wakeup bit.
【BIT7】 LED shutter enable/disable
0 = Disable
1 = Enable (Default)
【BIT6~BIT5】 MUST always be 01
【BIT4】 Sleep mode enable/disable
0 = Disable
1 = Enable (Default)
【BIT3】 Automatic enter sleep2 mode enable/disable
0 = Disable
1 = Enable (Default)
【BIT2】 Manual enter sleep2 mode, set “1” will enter sleep2 and this bit will be reset to “0”
【BIT1】 Manual enter sleep1 mode, set “1” will enter sleep1 and this bit will be reset to “0”
【BIT0】 Manual wake up from sleep mode, set “1” will enter wakeup and this bit will be reset to “0”
