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 field1: 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’.HLOCKLV HSYNC count asynchronousHLOCKLV > HSYNC count synchronous
