This Command indicates that user starts to transmit data. Then write to SRAM. While complete data transmission, user must send a
Datastop command (R11H). Then the chip will start to send data/VCOM for panel.

To stop data transmission, this command must be issued to check the data_flag.
Data_flag: Data flag of receiving user data.
0: Driver didn’t receive all the data.
1: Driver has already received all the one-frame data (DTM1 and DTM2).
After “Data Start” (10h) or “Data Stop” (11h) commands, BUSY signal will become “0” until display update is finished.
