Description
Ground connection
Connection for the crystal and capacitor used to form the crystal oscillator that generates
the internal synchronization signal. The oscillator can be selected with a command switch.
Outputs the horizontal synchronization signal (AFC). The output polarity can be selected
(metal option). Also functions as general output port (command switch).
Connection for the crystal and capacitor used to form the crystal oscillator that generates
the internal synchronization signal.
Outputs the vertical synchronization signal. The output polarity can be selected (metal
option). Also functions as general output port (command switch).
Enables/disables serial data input. Serial data is enabled when this pin is low (hysteresis
input). Pull-up resistor built in (metal option).
Serial data input (hysteresis input). Pull-up resistor built in (metal option).
Clock input for serial data input (hysteresis input). Pull-up resistor built in (metal option).
During input, switches between SECAM and other modes.
During output, functions as general output port or internal V output (command switch).
Low = other modes, high = SECAM mode
During input, switches between 525 scan lines and 625 scan lines.
During output, functions as general output port or character data output (command switch).
Low = 525 lines, high = 625 lines
Switches the color mode between NTSC and PAL.
During output, functions as general output port or frame data output (command switch).
Low = NTSC, high = PAL
Switch FSC between 3.58 MHz and 4.43 MHz.
During output, functions as general output port or halftone output (command switch).
Low = 3.58, high = 4.43
System reset input pin, low is active (hysteresis input).
Pull-up resistor built in (metal option).

VCO LC oscillator circuit coil and capacitor connection
Outputs the exclusive NOR of the horizontal synchronization signal (AFC) and CSYNC (sync
separator). The output polarity can be selected (metal option). Also functions as general
output port (command switch).
Power supply connection (+5 V: digital system power supply)
