This register indicates the ITU-RBT656 SAV and EAV status.
To detect error codes, set NTSC/PAL in the VS bit of VCM. If NTSC is set, reference the number of
data in the capture data count register (CDCN). If PAL is set, reference the number of data in the
capture data counter register (CDCP). If the reference data does not match the stream data , or
undefined Fourth word of SAV/EAV codes are detected, bits 4 to 0 of the video capture status register
(VCS) will be values as follows.
Bits 4-0 CE (Capture Error)
Indicates error occurred during video capture
