(3) Power OFF (PWR) (R02H)
Action W/R C/D D7 D6 D5 D4 D3 D2 D1 D0
Turning OFF the power 0 0 0 0 0 0 0 0 1 0
After the Power Off command, the driver will power off following the Power Off Sequence. This command will turn off charge
pump, T-con, source driver, gate driver, VCOM, and temperature sensor, but register data will be kept until VDD becomes OFF.
Source Driver output and Vcom will remain as previous condition, which may have 2 condition: 0V or floating.
(4) Power off sequence setting (PFS) (R03H)

T_VDS_OFF[1:0]: Power OFF Sequence of VDH and VDL.
00b: 1frame (Default) 01b: 2 frames 10b: 3frames 11b:4 frame
(5) Power ON (PON) (R04H)
Action W/R C/D D7 D6 D5 D4 D3 D2 D1 D0
Turning ON the Power 0 0 0 0 0 0 0 1 0 0
After the Power ON command, the driver will be powered ON following the Power ON Sequence. Refer to the Power ON
Sequence section. In the sequence, temperature sensor will be activated for one time sensing before enabling booster.
(6) Power ON Measure (PMES) (R05H)
Action W/R C/D D7 D6 D5 D4 D3 D2 D1 D0
0 0 0 0 0 0 0 1 0 1
This command enables the internal bandgap, which will be cleared by the next POF.
