3.13.6 Video Capture Channel x Field 2 Stop Register (VCASTOP2, VCBSTOP2)
The video capture channel x field 2 stop register (VCASTOP2, VCBSTOP2)
defines the end of the field 2-captured image. VCxSTOP2 is shown in
Figure 3–34 and described in Table 3–19.
These registers are not used in raw data mode or TSI mode because their
capture sizes are completely defined by the field 1 start and stop registers.
