• ADC
Input external interrupt request signal.
Either the rising edge or falling edge may
be selected as the effective edge for an
interrupt request.
Watchdog 32 kHz oscillator power supply.
Connects watchdog 32 kHz oscillator.
A 32 kHz crystal resonator should be
connected.
Pin for ground.
Pins 33 and 53 are connected within the
chip, but should also be connected to the
same potential externally taking into
condideration the characteristics of the
IDC (Image Display Controller).
Port 2A and serial interface input/outputs.
