Dear Ti :
1. I am using the ds90ub949a-q1 to light up the screen and use it to achieve screen touch. At the beginning, the screen display is normal.
However, after about 10 minutes of normal display, the screen signal will automatically disconnect.
At this time, when the 949 register is read again, no register can be read. You must restart 949 to read the value of the register again.
This is the normal 949 register

2. I hope ti can help me find out whether the register configuration is wrong, or some switches in 949 have errors.
3. Because my touch is not achieved through interruption, but through circulation, I may need to read screen registers frequently through 949. Want to know if this will affect 949?
Best Regards,
Xinyu
