INPUT
AY0
84
I 1 of 6 analog CVBS or 1of 3 S-video Y inputs.
AY1
86
I 1 of 6 analog CVBS or 1of 3 S-video Y inputs.
AY2
88
I 1 of 6 analog CVBS input or 1 of 3 S-video Y inputs or Y input for 3
wire component input
AC0
90
I 1 of 6 analog CVBS or 1 of 3 S-video C inputs.
AC1
92
I 1 of 6 analog CVBS or 1 of 3 S-video C inputs or Cb input for 3 wire
component input
AC2
94
I 1 of 6 analog CVBS or 1 of 3 S-video C inputs or Cr input for 3 wire
component input
XTALI
8
I Pin 1 for an external crystal or TTL clock input.
XTALO
7
O Pin 2 for an external crystal.
RST
10
I Chip reset. Active low signal.
OUTPUT (All output pins can be selectively three-stated)
Y0 - Y7, C0 - C7 45-48,53-56,33-
39,44
O Digital video outputs.
EXV0 - EXV7
16,27,28,61-63,
68,71
I/O Expanded digital video I/O port. Can be configured as an additional
8-bit output port (no scaling), or additional outputs of the main digital
output stream for 24 bit output modes, as an 8-bit input for direct
digital access of the down scaler.
HS1
26
I/O Programmable horizontal timing signal. One pulse every video line.
When the EXV port is configured as an input, this pin can be
programmed as an input.
HS2(IIC)
76
I/O Programmable horizontal timing signal. One pulse every video line.
At power up, this pin needs a 10 kΩ pull-down resistor to configure
the chip to operate in IIC mode.
VS
23
I/O Programmable vertical timing signal. When the EXV port is
configured as an input, this pin can be programmed as an input.
HAV
25
O Programmable horizontal active video flag.
VAV(OENC0) 3
I/O Programmable vertical active video flag.
During reset, the pin is an input and the logic state of this pin is
latched into the OENC[0] register bit. Use a 10 kΩ resistor for pull-up
or pull-down.
EHAV
5
O Valid pixel data flag. Polarity is programmable. Active when output
video data is valid.
