This register is read out serially after the 14 bits of NTSC WSS data, if WSS is enabled. It is
ignored during PAL WSS operation. Bit D0 is shifted out first.
This register is read out serially after the 14 bits of NTSC WSS data, if WSS is enabled. It is
ignored during PAL WSS operation. Bit D0 is shifted out first.
This 8-bit register is cascaded with Start H_Blank High Register to form a 10-bit
start_horizontal_blank register. It specifies the horizontal count (in 1x clock cycles) at which to
start ignoring pixel data each scan line. The leading edge of HSYNC is count 020
ister is ignored unless BLANK is configured as an output.
This 2-bit register is cascaded with Start H_Blank Low Register to form a 10-bit
start_horizontal_blank register. It specifies the horizontal count (in 1x clock cycles) at which to
start ignoring pixel data each scan line. The leading edge of HSYNC is count 020
ister is ignored unless BLANK is configured as an output.
This 8-bit register specifies the horizontal count (in 1x clock cycles) at which to start inputting
pixel data each scan line. The leading edge of HSYNC is count 000
unless BLANK is configured as an output.
