Bit Description
NVBEG [4:0]. Number of lines after l
rollover to set V high.
NVBEGSIGN.
NVBEGDELE. This bit delays the V bit going
high by one line relative to NVBEG (even field).
NVBEGDELO. This bit delays the V bit going
high by one line relative to NVBEG (odd field). 1
NVEND [4:0]. These bits control the number
of lines after l
NVENDSIGN.
NVENDDELE. This bit delays the V bit going
low by one line relative to NVEND (even field).
NVENDDELO. This bit delays the V bit going
low by one line relative to NVEND (odd field).
NFTOG [4:0]. These bits control the number
of lines after l
NFTOGSIGN.
NFTOGDELE. This bit delays the F transition
by one line relative to NFTOG (even field).
NFTOGDELO. This bit delays the F transition
by one line relative to NFTOG (odd field).
PVBEG [4:0]. These bits control the number of
lines after l
PVBEGSIGN.
PVBEGDELE. This bit delays the V bit going
high by one line relative to PVBEG (even field).
