A 21-bit value specifies the WORD offset from the start of the frame buffer for buffer 0
(packed mode), or Y components (planar mode) of the captured video. Buffer 0 is always
used, no matter double buffering is enabled or disabled. This register contains 16 lower-
order bits of the value. Bits 20-16 are located at CR17_4-0.
