S5D2650 Data Sheet
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 S5D2650 to correctly set the V component phase in PAL mode analog component video input mode,
PORTA (pin 58) need to be connected VSS. PORTA has to be configured as input (DIRA = 0) and connected to the
internal CBG signal (DATAA[2:0] = 3). Also S5D2650 supports progressive analog component input.
The following registers are required for analog component video input:
INSEL[2:0] = 6,7 PROG = 0(interlace), 1(progressive).
DATAA[2:0] = 3. CKILL[1:0] = 2. CDMLPF = 1.
SAT[7:0] = 79.
MNYCMB = 1. YCMBCO[2:0] = 4.
TSTCGN = 1. UOFFST[5:4] = VOFFST[5:4] = 3.
UOFFST[3:0] = C. VOFFST[3:0] = 2. VGAIN[7:0] = 1D. DMCTL[1:0] = 2 or 3
