Description
Port 0: Port 0 is a 6-bit I/O port with user-configurable outputs. During reset Port 0
latches are configured in the input only mode with the internal pull-up disabled. The
operation of Port 0 pins as inputs and outputs depends upon the port configuration
selected. Each port pin is configured independently. Refer to
configurations”
The Keypad Interrupt feature operates with Port 0 pins.
All pins have Schmitt triggered inputs.
Port 0 also provides various special functions as described below:
P0.0 — Port 0 bit 0.
CMP2 — Comparator 2 output.
KBI0 — Keyboard input 0.
P0.1 — Port 0 bit 1.
CIN2B — Comparator 2 positive input B.
KBI1 — Keyboard input 1.
AD10 — A/D channel 1, input 0
P0.2 — Port 0 bit 2.
CIN2A — Comparator 2 positive input A.
KBI2 — Keyboard input 2.
AD11 — A/D channel 1, input 1
P0.3 — Port 0 bit 3.
CIN1B — Comparator 1 positive input B.
KBI3 — Keyboard input 3.
AD12 — A/D channel 1, input 2.
P0.4 — Port 0 bit 4.
CIN1A — Comparator 1 positive input A.
KBI4 — Keyboard input 4.
AD13 — A/D channel 1, input 3.
DAC1 — Digital to analog converter 1 output.
P0.5 — Port 0 bit 5.
CMPREF — Comparator reference (negative) input.
KBI5 — Keyboard input 5.
CLKIN — External clock input.
