(Port A)
8-bit I/O port. I/O can be
set in a unit of single bit.
Incorporation of the
pull-up resistance can be
set through the software
in a unit of 4 bits.
(8 pins)
(Port B)
7-bit I/O port in which I/O
can be set in a unit of
single bit. Also, an
uppermost bit (PB7)
exclusively for output.
Incorporation of pull-up
resistor can be set
through the software in a
unit of 4 bits.
(8 pins)
(Port C)
8-bit I/O port. I/O can be set in a unit of single bit. Capable of driving
12mA sink current. Incorporation of pull-up resistor can be set through
the software in a unit of 4 bits.
(8 pins)
(Port D)
8-bit I/O port. I/O can be set in a unit of single bits. Incorporation of pull-
up resistor can be set through the software in a unit of 4 bits.
(8 pins)
(Port E)
6-bit port. Lower 4 bits
are for inputs; upper
2 bits are for outputs.
(6 pins)
(Port F)
8-bit I/O port. I/O can be set in a unit of single bit. Incorporation of
pull-up resistor can be set through the software in a unit of 4 bits.
(8 pins)
