Table 4.
1. Standard on hardware reset is NTSC; any standard modification selects automatically the right
Table 5.
1. In VSYNC-only based slave mode (sync[2:0]=”100”), HSYNC is nevertheless needed as an input.
polh : synchro: active edge of HSYNC selection (when input) or polarity of HSYNC (when
output)
polv : synchro: active edge of ODDEV/VSYNC selection (when input)

parameters for correct subcarrier generation.
(*) 0 = HSYNC is a negative pulse (128 Tpix_clk wide) or falling edge is active
1 = HSYNC is a positive pulse (128 Tpix_clk wide) or rising edge is active
0 = falling edge of ODDEV flags start of field1 (odd field) or VSYNC is active low
(*) 1 = rising edge of ODDEV flags start of field1 (odd field) or VSYNC is active high
