Function
Same as Register 0E bit 7, but read-only.
Select 625 lines per frame. When HIGH, the encoder assumes 625 line per
frame. When LOW, 525 lines per frame are assumed.
PAL select. When HIGH, Phase alternate line (PAL) operation is selected.
When LOW, operation conforms to NTSC standards.
Setup enable. When HIGH, a 7.5 IRE Pedestal is added to the output video.
when LOW, no pedestal is added.
Luminance gain settings are adjusted to conform to the following NTSC and
PAL standards:
0 0 NTSC without SETUP
0 1 NTSC-A and PAL-M
1 0 PAL-I and PAL-N
1 1 Reserved
Chrominance gain settings are adjusted to conform to the following NTSC and

Function
Horizontal sync tip length. This 8-bit register holds a value extending from 0 to
255 PCK cycles.
Breezeway length. This 8-bit register holds a value extending from 0 to 255
PCK cycles.
Burst length. This 8-bit register holds a value extending from 0 to 255 PCK
cycles.
Color back porch length. This 8-bit register holds a value extending from 0 to
255 PCK cycles.
Extended color back porch 8 LSBs. This 8-bit register holds the LSBs of a
10-bit value extending from 0 to 1023 PCK cycles. The two MSBs are located in
control register 18.
Active video 8 LSBs. This 8-bit register holds the LSBs of a 10-bit value
extending from 0 to 1023 PCK cycles. The two MSBs are located in control
register 18.
Active video start 8 LSBs. This 8-bit register holds the LSBs of a 10-bit value
which is the initial half active video length extending from 0 to 1023 PCK cycles.
The two MSBs are located in control register 18.
Active video end 8 LSBs This 8-bit register holds the LSBs of a 10-bit value
which is the end half active video length extending from 0 to 1023 PCK cycles.
The two MSBs are located in control register 18.
