HSEP1: HSYNC Separator Control Register 1
x’007ECE’
(HSEP1W
x’007EEE’)
HSFREQ[10:0]: Correction HSYNC frequency
Set the correction HSYNC cycle in this field in HSYNC separator sam-
pling clock units. The valid range is x’000’ to x’7FF’, and the recom-
mended setting is x’010C’.
HSEP2: HSYNC Separator Control Register 2
x’007ED0’
(HSEP2E
x’007EF0’)
HCLOSEE[9:0]: Start position for HSYNC detection
Set the position in HSYNC separator sampling clock units. The valid range
is x’000’ to x’3FF’, and the recommended setting is x’00E4’.
FIELD: Field Detection Control Register
x’007ED2’
(FIELDW
x’007EF2’)
ODDEVEN: Field detection signal
0: Odd field
1: Even field
VPHASE[9:0]: Phase difference setting for VSYNC and HSYNC
Set the phase difference in HSYNC separator sampling clock units. The
valid range is x’000’ to x’3FF’.
HLOCKLV: Sync Separator Detection Control Register 1
x’007ED4’
(HLOCKLVW
x’007EF4’)
HLOCKLV[8:0]: Sync separator detection threshold
This value is compared to the count of the corrected HSYNC. The valid
range is x’000’ to x’1FF’, and the recommended setting is x’0008’.
