TDA8754
Triple 8-bit video ADC up to 270 Msample/s
9.11 Coast register
Remark: When POSTCOAST[4:0] = PRECOAST[2:0] = 0, then the coast pulse equals
the VSYNC input.
9.12 Horizontal sync selection register

TESTCNT
this bit is used to test the pixel counter
0 = normal mode
1 = test mode
2
BYSEPA
enables the sync separator for the PLL reference to be bypassed
0 = Hsync from the separator
1 = bypass of the sync separator
1
HSSEL
enables either the HSYNC or CHSYNC input signal to be selected
0 = HSYNC input
1 = CHSYNC input
0
HSS
enables either the HSYNC or CHSYNC input signal to be inverted
0 = non-inverted
1 = inverted
