(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.
After the Power Off command, BUSY_N signal will drop from high to low. When finish the power off sequence, BUSY_N signal will rise
from low to high.
This command will turn off charge pump, T-con, source driver, gate driver, VCOM, and temperature sensor, but register data and SRAM
data will kept until VDD OFF.
Source Driver output and Vcom will base on previous condition, which may have 2 condition: 0V or floating.
(4) Power OFF Sequence Setting (R03H)
Action W/R C/D D7 D6 D5 D4 D3 D2 D1 D0
Setting Power OFF Sequence

(5) Power ON (R04H)
Action W/R C/D D7 D6 D5 D4 D3 D2 D1 D0
Turnning ON the Power 0 0 0 0 0 0 0 1 0 0
After the Power ON command, driver will power on based on the Power ON Sequence.
After Power On command, BUSY_N signal will drop from high to low. When finishing the power off sequence, BUSY_N signal will rise
from low to high.
(6) Power ON Measure (PMES) (R05H)
Action W/R C/D D7 D6 D5 D4 D3 D2 D1 D0

If user want to read temperature sensor or detect low power in power off mode, user has to send this command. After power on measure
command, driver will switch on relevant commend with Low Power detection (R51H) and temperature measurement. (R40H).
