Input
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.
Input Ground pin for the A/D and D/A converters.
Connect to system ground (0 V).
Input
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.
Input/ Port 1: Eight input/output pins. The direction of
output each pin can be selected in the port 1 data
direction register (P1DDR).
Input/ Port 2: Eight input/output pins. The direction of
output each pin can be selected in the port 2 data
direction register (P2DDR).
Input/ Port 3: Eight input/output pins. The direction of
output each pin can be selected in the port 3 data
direction register (P3DDR).
Input/ Port 4: Eight input/output pins. The
output direction of each pin can be selected in the port
4 data direction register (P4DDR).
