Functions
(Port G)
8-bit I/O port. I/O can be set in a unit of single bits.
Incorporation of pull-up resistor can be set through the software in a unit
of 4 bits.
(4 pins)
(Port D)
8-bit output ports.
(8 pins)
FDP segment signal outputs.
(8 pins)
FDP segment signal outputs. (4 pins)
Outputs for FDP timing signals/segment signals.
(8 pins)
FDP timing signal outputs.
FDP voltage supply when incorporated resistor is set by mask option.
Crystal connectors for system clock oscillation. When the clock is
supplied externally, input to EXTAL; opposite phase clock should be
input to XTAL.
Crystal connectors for 32kHz timer/counter clock oscillation. Set 32kHz
crystal oscillator between TEX and TX. For usage as event input, attach
clock source to TEX, and open TX.
Low-level active, system reset.
NC. Under normal operation, connect to VDD.
Positive power supply for A/D converter.
Reference voltage input for A/D converter.
A/D converter GND.
Positive power supply.
GND.
