3.13.4 Video Capture Channel x Field 1 Stop Register (VCxSTOP1)

The video capture channel x field 1 stop register (VCxSTOP1) defines the end of the field 1-captured
image or the end of the raw data or TCI packet.
In raw capture mode, the horizontal and vertical counters are combined into a single counter that keeps
track of the total number of samples received.
In TCI capture mode, the horizontal and vertical counters are combined into a single data counter that
keeps track of the total number of bytes received. The capture starts when a SYNC byte is detected. The
data counter counts bytes as they are received. The FRMC bit (in VCxSTAT) gets set each time a packet
has been received.
The video capture channel x field 1 stop register (VCxSTOP1) is shown in
Table 3-17.
