Tool/software: Code Composer Studio
In my project, AM3894 VGA has chance to output blank screen after working for several hours.
The temperature of AM3894 and its DDR are within the specification, about 50-60 degree Celsius.
When blank screen occurs, one of the HDVPSS registers will be changed.
The register is Bit1 HDCOMP_UNDERFLOW_STAT, as shown in the attachment.
Reinitializing the HDVPSS can return VGA to normal operation.
Can someone help me explain the meaning of this register? What happen will let this register change?
