Name and Function
37
76
Input Analog power: The analog power supply
pin for the A/D converter and D/A
converter.
When the A/D and D/A converters are not
used, this pin should be connected to the
system power supply (+5 V or +3 V).
36
77
Input Analog reference voltage: The reference
power supply pin for the A/D converter and
D/A converter.
When the A/D and D/A converters are not
used, this pin should be connected to the
system power supply (+5 V or +3 V).
46
67
Input Analog ground: The ground pin for the
A/D converter and D/A converter. This pin
should be connected to the system power
supply
(0 V).

Output
Port 1: Eight input/output pins. The data
direction of each pin can be selected in the
port 1 data direction register (P1DDR).
These pins have built-in MOS input pull-
ups, and also have LED drive capability.
