P0[0]/CMP2/KBI0/AD05
Port 0: Port 0 is an 8-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
Section 7.13.1 “Port configurations”
details.
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.
AD05 — ADC0 channel 5 analog input.
P0[1] — Port 0 bit 1.
CIN2B — Comparator 2 positive input B.
KBI1 — Keyboard input 1.
AD00 — ADC0 channel 0 analog input.
