Circuit
type
Function
A
Main clock crystal oscillator pins (max. 10 MHz)
B
Subclock crystal oscillator pins (32.768 kHz)
C
Operating mode selection pins
Connect to VSS (GND) when using.
J
Reset I/O pin
“L” is output from this pin by an internal source.
The internal circuit is initialized by the input of “L”.
D
General-purpose I/O ports
Also serve as an external interrupt input (wake-up
function).
External interrupt input is hysteresis input.
E
General-purpose I/O ports
Also serve as the input for the OP amp
F
General-purpose I/O ports
E
General-purpose I/O ports
Also serve as the input for the A/D converter.
G
General-purpose I/O ports
Also serve as the A/D converter input and the
output for the OP amp.
H
General-purpose I/O ports
Also serve as an LCD controller/driver segment
output.
F
General-purpose I/O port
The output type can be switched between N-ch
open-drain and CMOS. Also serves as an 8-bit
PWM timer.
F
General-purpose I/O ports
The output type can be switched between N-ch
open-drain and CMOS. Also serves as an 8/16-bit
timer/counter.
