Name and Function
Data output pins.
Receive data (channel 0, 1):
Data input pins.
Serial clock (channel 0, 1):
Clock I/O pins.
Analog 7 to 0: Analog input pins.
A/D conversion external trigger input:
Pin for input of an external trigger to
start A/D conversion.
output pins.
This is the power supply pin for the
A/D converter and D/A converter.
When the A/D converter and D/A
converter are not used, this pin
should be connected to the system
power supply (+5 V).
This is the ground pin for the A/D
converter and D/A converter.
This pin should be connected to the
system power supply (0 V).
This is the reference voltage input pin
for the A/D converter and D/A
converter.
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 2: An 8-bit I/O port. Input or
output can be designated for each bit
by means of the port 2 data direction
register (P2DDR).
