See description of FR33.
This bit is effective when FR37 bit 6 is set to 0.
0: FP VSync (FLM) delay enable
1: FP VSync (FLM) delay disable
0: FP VSync (FLM) is generated using FR37 bit 7 and FP VSync (FLM) Delay (FR36 bits
6-4 and FR34) .
1: FP VSync (FLM) is the same as CRT VSync. FR37 bit 7 is ignored in this case.
These bits are effective only if bit 6 is 0.
These bits should always be written to with a value of zero.
