Circuit
type
Function
A
Main clock oscillator pins
C
Operating mode selection pins
Connect directly to VSS.
D
Reset I/O pin
This pin is an N-ch open-drain output type with a pull-
up resistor and a hysteresis input type. “L” is output
from this pin by an internal reset source. 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 2 input is hysteresis input.
E
General-purpose I/O ports
Also serve as external interrupt 1 input.
External interrupt 1 input is hysteresis input.
F
General-purpose I/O ports
H
N-ch open-drain general-purpose I/O port
Also serves as the external clock input for the timer.
The peripheral is a hysteresis input type.
I
N-ch open-drain general-purpose I/O port
I
N-ch open-drain general-purpose I/O port
Also serves as a timer output.
H
N-ch open-drain general-purpose I/O port
Also serves as the data input for the 8-bit serial I/O.
The peripheral is a hysteresis input type.
I
N-ch open-drain general-purpose I/O port
Also serves as the data output for the 8-bit serial I/O.
H
N-ch open-drain general-purpose I/O port
Also serves as the clock I/O for the 8-bit serial I/O.
The peripheral is a hysteresis input type.
I
N-ch open-drain general-purpose I/O port
I
N-ch open-drain general-purpose I/O port
Also serves as a buzzer output.
