Name and Function
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).
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).
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).
Port 4: An 8-bit input port.
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).
Port 9: An 8-bit input port.
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).
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).
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).
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).
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).
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).
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).
