FUNCTION
Analog 5V supply pin
Analog ground pin
Preset input pin for stand alone
operation
Preset input pin for stand alone
operation
This pin can be configured as an input
or output via the control register (bits
B8 and B9). If configured as output, it
can be programmed to give analog or
digital (even/odd) field information. If
configured as input, it can be used to
set analog fields (1 and 2) or (3 and 4).
External chroma lock input
Digital 5V supply pin
Digital ground pin
Vertical synchronization signal. Pin is
configured as input in external slave
mode and as output in master and
internal slave (CCIR656) modes.
Polarity and function are programmed
in control register in bits B10, B17,
B26, and B28.
Horizontal synchronization signal. Pin
is configured as input in external slave
mode and as output in master and
internal slave (CCIR656) modes.
Polarity and function are programmed
in control register in bits B15, B25,
B28, and B29.
