Type Symbol I/O Name and Function
A/D converter,
D/A converter
Vref Input A/D converter and D/A converter reference voltage
input pin.
When the A/D converter and D/A converter are not
used, this pin should be connected to the system
power supply (+5 V).
I/O ports P17 to P10 I/O Port 1: An 8-bit I/O port. Input or output can be
designated for each bit by means of the port 1 data
direction register (P1DDR).
P37 to P30 I/O Port 3: An 8-bit I/O port. Input or output can be
designated for each bit by means of the port 3 data
direction register (P3DDR).
P47 to P40 Input Port 4: An 8-bit input port.
P77 to P70 I/O Port 7: An 8-bit I/O port. Input or output can be
designated for each bit by means of the port 7 data
direction register (P7DDR).
P97 to P90 Input Port 9: An 8-bit input port.
PA3 to PA0 I/O Port A: A 4-bit I/O port. Input or output can be
designated for each bit by means of the port A data
direction register (PADDR).
PB7 to PB0 I/O Port B: An 8-bit I/O port. Input or output can be
designated for each bit by means of the port B data
direction register (PBDDR).
PC7 to PC0 I/O Port C: An 8-bit I/O port. Input or output can be
designated for each bit by means of the port C data
direction register (PCDDR).
PD7 to PD0 I/O Port D: An 8-bit I/O port. Input or output can be
designated for each bit by means of the port D data
direction register (PDDDR).
PE7 to PE0 I/O Port E: An 8-bit I/O port. Input or output can be
designated for each bit by means of the port E data
direction register (PEDDR).
PF7 to PF0 I/O Port F: An 8-bit I/O port. Input or output can be
designated for each bit by means of the port F data
direction register (PFDDR).
PG4 to PG0 I/O Port G: An 5-bit I/O port. Input or output can be
designated for each bit by means of the port G data
direction register (PGDDR).
