Name and Function
Analog 15 to 0: Analog input pins.
A/D conversion external trigger input: Pin for input of
an external trigger to start A/D conversion.
A/D converter power supply pin.
When the A/D converter are not used, this pin should
be connected to the system power supply (+5 V).
Analog circuit ground and reference voltage
A/D converter ground and reference voltage.
Connect to system power supply (0 V).
A/D converter reference voltage input pin.
When the A/D 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).
