(8) Deep Sleep (DSLP) (R07H)
Action W/R C/D D7 D6 D5 D4 D3 D2 D1 D0
Deep Sleep
0 0
0 0 0 0 0 1 1 1
0 1 1 0 1 0 0 1 0 1
After this command is transmitted, the chip would enter the deep-sleep mode to save power.
The deep sleep mode would return to standby by hardware reset.
The only one parameter is a check code, the command would be executed if check code = 0xA5.
(9) Data Start Transmission 1 (DTM1) (R10H)

This command starts transmitting data and write them into SRAM. To complete data transmission, command DSP (Data
transmission Stop) must be issued. Then the chip will start to send data/VCOM for panel.
In B/W mode, this command writes “OLD” data to SRAM.
In B/W/Red mode, this command writes “B/W” data to SRAM.
In Program mode, this command writes “OTP” data to SRAM for programming.
(10) Data Stop (DSP) (R11H)
Action W/R C/D D7 D6 D5 D4 D3 D2 D1 D0
Stopping data

1 1 Data_flag - - - - - - -
To stop data transmission, this command must be issued to check the data_flag.
Data_flag: Data flag of receiving user data.
