Hello Haiwen,

Could you elaborate on your question? Do they want to read the register to confirm if the device has been restarted correctly?

Customer wants to know if device is working correctly. If not, they can restart it immediately.

Hello Haiwen,

They can read the status register 0xE5 to see if some error has been detected. Note that this register should be cleared by writing 0xFF before reading a correct status.

Hello Haiwen,

Please, read the complete register map and send the values. When the screen is shutdown, are the read values different than the programmed?
