When in digital input mode, all programmable timing registers (such as HAVB,HAVE, HS2B etc.) are still functional.
If HS1 and VS are programmed as inputs, the associated output timing controls such as HS1B,E will have no
effect. An example of horizontal timing for digital input is shown in Figure 4.

1.1.5. Additional Information for Analog Component Video Input
For the S5D0127X01 to correctly set the V component phase in analog component video input mode, PID (pin 17)
and PORTA (pin 58) need to be connected together. PORTA has to be configured as input (
DIRA
= 0) and
connected to the internal CBG signal (
DATAA
[2:0] = 3).
It is also recommended that external clamp circuit be used for Cb and Cr inputs (before the coupling caps) and the
internal chroma clamp be disabled (
COFFENB
= 1) due to slight Cb/Cr leakage.
