Reserved (R/W)
Reserved for assisting memory control, works only when
MemConf is set as two-field memory capture. To be turned
on only when there is memory I/O timing conflict.
Suggested value is 81h for 1024x768 input / overcan PAL
output, and 00h for other modes.

<7:0>
For input resolution of 640x480 or 800x600, the value of (GinHTotal * 8) equals to
(reg#28h<6:0> * 16). For higher input resolution, PllDiv needs to be lower than the
Detected Horizontal Total so as not to exceed the speed limit of the field memory.
