Blank level, as measured at the low-pass-filtered A/D output during each line

color back porch. For a standard video input, its decimal value will be
approximately 60 (NTSC) or 64 (PAL). [TMC22071A bits 55:48.]
Reg 07 Reserved
Reg 08 Standard and Clock Rate Select

V_STD
Video Standard
. These two control bits select the incoming video standard, viz:
00 NTSC, NTSC-EIAJ (power-on default)
01 PALM (Brazil)
10 PALB,G,H,I
11 PALN (Argentina)
[With bits 5:4, these bits cover all functions of TMC22071A bits 3:1.]
Pixel Clock/Sample Rate
. Pixel (sample) rate selector, as follows:
5:4
CK_RATE
00 12.27 MHz (power-on default; 525-line VGA)
01 13.5 MHz (D1 television rate)
10 14.75 MHz (625-line square-pixel VGA) TMC2072-1 only
11 15.0 MHz TMC2072-1 only
Note: The 12.27 MHz pixel rate is reserved for 525-line television standards
(NTSC, PAL-M), whereas the 14.75 and 15.0 MHz rates are for 625-line
standards (all other PAL) only. Bit combinations 0x1x and 1x00 may yield stable
composite data samples, sync pulses, and pixel clock, but no useful color
subcarrier information.
Freerun vs. Genlock Operation
. LOW (power-on default): Standard genlock
mode, in which the PXCK, GHSYNC, and GVSYNC lock to the incoming video
’
s
observed sync pattern. HIGH: GHSYNC is counted down from a free-running
PXCK, which is unrelated to the incoming video. [TMC22071A bit 26.]
Genlock Reference Signal Enable
. LOW (power-on default): Loop-predicted
subcarrier phase and frequency data (GRS) are sent over CVBS during each
horizontal sync pulse. HIGH: GRS data suppressed, such that the CVBS
datastream is just the digitized incoming video signal. [TMC22071A bit 33.]
HIGH (power-on default): vertically low-pass filtered digital porch clamp enabled.
LOW: digital clamp disabled [TMC22071A bit 34, except that the TMC22071A
clamp has no vertical filter.]
Master Software Reset Control
. HIGH (power-on default & self-reset state):
normal operation. LOW: Bringing this
“
one-shot
”
control low resets all internal
state machines and registers except the microprocessor control bits themselves.
The bit then sets itself high, permitting normal operation. (Because it
automatically returns to the high state, this bit will always appear as a 1 when
read through the microprocessor port.) [TMC22071A bit 0.]

Hsync Lead/lag Control
(in one-pixel = two-PXCK increments). Power-on
default = 80 Hex. To advance (delay) GHSYNC and GVSYNC relative to the
video input, decrease (increase) the value. Program code 79h, with sub pixel
control = 0.5 will align the GHSYNC output with the falling sync edge of the input
video. [TMC22071A bits 24:17.]
