Circuit type
Function
A
Main clock crystal oscillator pins
B
Subclock oscillation pins (32.768 kHz)
C
Operation mode selecting pins
Connect directly to VCC or VSS.
D
Reset I/O pin
This pin is of an N-ch open-drain output type with pull-up
resistor and of hysteresis input type.
“L” is output from this pin by an internal reset source (optional
function).
The internal circuit is initialized by the input of “L”.
E
General-purpose I/O ports
Also serve as an external interrupt 2 input (wake-up function).
External interrupt input is a hysteresis input.
F
General-purpose I/O ports
H
General-purpose output ports
G
General-purpose I/O port
Also serves as the clock I/O for the 8-bit serial I/O.
This port is of hysteresis input type.
G
General-purpose I/O port
Also serves as the data output for the 8-bit serial I/O.
This port is of hysteresis input type.
G
General-purpose I/O port
Also serves as the data input for the 8-bit serial I/O.
This port is of hysteresis input type.
G
General-purpose I/O port
Also serves as an external clock input for a 8-bit timer/
counter.
This port is of hysteresis input type.
G
General-purpose I/O port
Also serves as the overflow output for the 8-bit timer/counter
and an external interrupt 1 input.
This port is of hysteresis input type.
G
General-purpose I/O ports
Also serve as an external interrupt 1 input.
These ports are of hysteresis input type.
