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 “11100” = Force enter sleep23 “1x010” = Force enter sleep13 (If Slp2_enh is set, the mouse sensor still enter the sleep2 automatically.) “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 256 ms (±20%) not moving during normal mode, the mouse sensor will enter sleep1 mode, and keep on sleep1 mode until moving is detected or wakeup is asserted. Note that the entering time depends on the setting of Enter_Time register. 2. Enable sleep mode full function, which is 3 modes will be used, normal mode, sleep1 mode and sleep2 mode. After 256 ms (±20%) not moving during normal mode, the mouse sensor will enter sleep1 mode, and keep on sleep1 mode until moving is detected or wakeup is asserted. And after 61 sec (±20%) not moving during sleep1 mode, the mouse sensor will enter sleep2 mode, and keep on sleep2 mode until detect moving or force wakeup to normal mode. Note that the entering time depends on the setting of Enter_Time register. 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 bit, which was set to 1, will be reset to 0 by internal signal. 4. The user can clear Slp_enh/Slp2_enh bit to make the mouse sensor enter normal mode. If the user clears Slp_enh/Slp2_enh bit during normal mode, the mouse sensor will keep its status. If the user clears Slp_enh/Slp2_enh bit during sleep mode, the mouse sensor will enter normal mode after it detect any movement or the user sets Wakeup bit. Field Name Description LEDsht_enh LED shutter enable/disable 0 = Disable 1 = Enable (Default) Bit [6:5] MUST always be 01 Slp_enh Sleep mode enable/disable 0 = Disable 1 = Enable (Default) Notes Slp2_enh Automatic enter sleep2 mode enable/disable 0 = Disable 1 = Enable (Default) |
