The video capture channel x field 2 stop register (VC xSTOP2) defines the end of the field 2-captured
image.
These registers are not used in raw data mode or TCI mode because their capture sizes are completely
defined by the field 1 start and stop registers.
The video capture channel x field 2 stop register (VC xSTOP2) is shown in Figure 3-26 and described in
Table 3-19 .
