Name and Function
Analog output: Analog output pins for D/A converter.
Analog power supply: A/D converter and D/A converter
power supply 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).
Analog ground: Ground pin for A/D converter and D/A
converter.
Connect to system power supply (0 V).
Analog reference power supply: 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: A 6-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 9: A 4-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).
