Port 0: Port 0 is a 7-bit I/O port with a user-configurable output type.
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
and
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 — ADC1 channel 0 analog input.
P0.2 — Port 0 bit 2.
CIN2A — Comparator 2 positive input A.
KBI2 — Keyboard input 2.
AD11 — ADC1 channel 1 analog input.
P0.3 — Port 0 bit 3.
CIN1B — Comparator 1 positive input B.
KBI3 — Keyboard input 3.
AD12 — ADC1 channel 2 analog input.
P0.4 — Port 0 bit 4.
CIN1A — Comparator 1 positive input A.
KBI4 — Keyboard input 4.
AD13 — ADC1 channel 3 analog input.
DAC1 — DAC1 analog output.
P0.5 — Port 0 bit 5.
CMPREF — Comparator reference (negative) input.
KBI5 — Keyboard input 5.
CLKIN — External clock input.
