Description
Video input signal CRC error detection (1: Detection)
Video input signal CRC error accumulation in 1 video
frame
The GS1503B will set the VIDEO_DET external pin HIGH when three consecutive
TRS are detected in the input video signal. Also, the VIDEO_DET bit of Host
Interface register 000h is set HIGH.
The GS1503B will set the CRC_ERR external pin HIGH when a CRC error is
detected in the input video signal. Also, the CRC_ERR bit 5 of Host Interface
register 000h is set HIGH. The number of CRC errors accumulated in one video
frame can be read form CRC_CNT[11:0] in Host Interface registers 006h and 007h.
