A/D conversion
D/A converter
Power supply pin for the A/D and
D/A converters. Connect to the system power
supply (+5 V) when not using the A/D and
D/A converters.
Ground pin for the A/D and D/A converters.
Connect to system ground (0 V).
Reference voltage input pin for the A/D and
D/A converters. Connect to the system power
supply (+5 V) when not using the A/D and
D/A converters.
Port 1: Eight input/output pins. The direction of
each pin can be selected in the port 1 data
direction register (P1DDR).
Port 2: Eight input/output pins. The direction of
each pin can be selected in the port 2 data
direction register (P2DDR).
Port 3: Eight input/output pins. The direction of
each pin can be selected in the port 3 data
direction register (P3DDR).
Port 4: Eight input/output pins. The
direction of each pin can be selected in the port
4 data direction register (P4DDR).
