Bits 15-0 Capture V Frame Buffer 1 Start Address Low
A 21-bit value specifies the WORD offset from the start of the frame buffer for V
components (planar mode) of the captured video. It is not used if the captured video is in
packed mode. Buffer 1 is not used if double buffering is disabled. This register contains 16
lower-order bits of the value. Bits 20-16 are located at CR21_4-0.
