I/O
−
Digital ground
I Crystal oscillator connection (2fsc or 4fsc)
O Crystal oscillator connection (2fsc or 4fsc)
I Crystal oscillator input switching L: crystal oscillator mode, H: external clock mode
O Blank signal output Outputs a composite sync signal when MOD0 is high.
I Connections for the coil and capacitor that form the oscillator that generates the character output dot clock.
O Connections for the coil and capacitor that form the oscillator that generates the character output dot clock.
I Character signal output
Enable input for serial data input Serial data input is enabled when low.
I
A pull-up resistor is built in (hysteresis input).
I Clock input for serial data I/O A pull-up resistor is built in (hysteresis input).
I Serial data input A pull-up resistor is built in (hysteresis input).
−
Analog power supply
O Composite video signal output
−
Must be either connected to ground or left open.
I Composite video signal input
−
+5 V digital power supply
I Video signal input for the built-in sync separator circuit
O Built-in sync separator circuit bias voltage monitor pin
O Built-in sync separator circuit composite sync signal output
I Inputs a vertical synchronization signal created by integrating the SEPOUT pin output signal.
The setting indicated by this pin takes priority in switching between the NTSC, PAL, PAL-M and PAL-N
I formats. A low level selects NTSC after a reset. The microprocessor command NTSC, PAL, PAL-M, or PAL-
N setting is valid. High = PAL-M format.
I Controls whether or not the VSYNC signal is input to the SEPIN input. Low = VSYNC input, high = VSYNC not input.
