Pins for connecting the crystal resonator for the main
clock. To use an external clock, input the signal to X0 and
leave X1 open.
Memory access mode setting input pins.
Connect the pin directly to Vss.
Reset I/O pin. The pin is N-ch open-drain type with pull-
up resistor and a hysteresis input as well. The pin outputs
the “L” level when an internal reset request is present.
Inputting an “L” level initializes internal circuits.
General-purpose CMOS I/O ports.
These pins also serve as an input (wake-up input) of
external interrupt 2 or as an A/D converter analog input.
The input of external interrupt 2 is a hysteresis input.
General-purpose CMOS I/O ports.
These pins also serve as an input (wake-up input) of
external interrupt 2. The input of external interrupt 2 is a
hysteresis input.
General-purpose CMOS I/O port.
This pin also serves as the clock I/O pin for the UART or
8-bit serial I/O. The resources is a hysteresis input.
General-purpose CMOS I/O port.
This pin also serves as the data output pin for the UART
or 8-bit serial I/O.
General-purpose CMOS I/O port.
This pin also serves as the data input pin for the UART or
8-bit serial I/O. The resources is a hysteresis input.
General-purpose CMOS I/O port.
This pin also serves as the external clock input pin for the
8/16-bit capture timer/counter. The resource is a
hysteresis input.
General-purpose CMOS I/O port.
This pin also serves as the output pin for the 8/16-bit
capture timer/counter or as the input pin for external
interrupt 1. The resource is a hysteresis input.
General-purpose CMOS I/O ports.
These pins also serve as the input pins for external
interrupt 1. The resource is a hysteresis input.
General-purpose CMOS I/O port.
This pin also serves as the buzzer output pin or the 12-bit
programmable pulse generator output.
General-purpose CMOS I/O port.
The pin also serves as the 8-bit PWM output pin.
General-purpose CMOS I/O ports. These pins can also
be used as N-channel open-drain ports.
The pins also serve as A/D converter analog input pins.
