Reset input Input
A “L” on this input resets the microcomputer.
Clock input
Clock output
Input
Output
These pins are provided for the main clock generating circuit.Connect
a ceramic resonator or crystal between the XIN and the XOUT pins. To
use an externally derived clock, input it to the XIN pin and leave the
XOUT pin open.
Analog power
supply input
I/O port P0
Input/output
This pin is a power supply input for the A-D converter. Connect this
pin to VCC.
This is an 8-bit CMOS I/O port. It has an input/output port direction
register that allows the user to set each pin for input or output
individually. When set for input, the user can specify in units of four bits
via software whether or not they are tied to a pull-up resistor.
I/O port P2 Input/output This is an 8-bit I/O port equivalent to P0.
I/O port P3
I/O port P4
Input/output This is an 8-bit I/O port equivalent to P0. Pins in this port function as
external interrupt pin, HSYNC counter I/O pins, and A-D converter input
pins as selected by software.
Input/output This is an 8-bit I/O port equivalent to P0. Pins in this port function as A-D
converter input pins as selected by software.

I/O port P5
I/O port P6
Input/output ^{This is a 4-bit I/O port equivalent to P0. P57 in this port functions as}
UART0 I/O pin as selected by software.
Input/output
This is a 3-bit I/O port equivalent to P0. Pins in this port also function as
UART0 and multi-master I²C-BUS interface 0 I/O pins as selected by
software.

Input/output
Input/output
This is a 5-bit I/O port equivalent to P0 (P70 and P71 are N-channel
open-drain output). Pins in this port also function as timers A2 and A3,
UART2, multi-master I²C-BUS interface 0 I/O pins as selected by
software.
P82 is I/O port with the same functions as P0.
P82 can be made to function as the I/O pin for the input pins for external
interrupts as selected by software.
This is an 3-bit I/O port equivalent to P0. Pins in this port also function
as Timer B0 input pin, D-A converter output pins, and multi-master I²C-
BUS interface 1 I/O pins as selected by software.
