Type Description

I/O 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

7.16.1 “Port configurations” and Table 12 “Static characteristics” for details.

The Keypad Interrupt feature operates with Port 0 pins.

All pins have Schmitt trigger inputs.

Port 0 also provides various special functions as described below:

I/O P0.0 — Port 0 bit 0.

O CMP2 — Comparator 2 output

I

KBI0 — Keyboard input 0.

I

AD01 — ADC0 channel 1 analog input.

I/O P0.1 — Port 0 bit 1.

I

CIN2B — Comparator 2 positive input B.

I

KBI1 — Keyboard input 1.

I

AD10 — ADC1 channel 0 analog input.

I/O P0.2 — Port 0 bit 2.

I

CIN2A — Comparator 2 positive input A.

I

KBI2 — Keyboard input 2.

I

AD11 — ADC1 channel 1 analog input.

I/O P0.3 — Port 0 bit 3. High current source.

I

CIN1B — Comparator 1 positive input B.

I

KBI3 — Keyboard input 3.

I

AD12 — ADC1 channel 2 analog input.

I/O P0.4 — Port 0 bit 4. High current source.

I

CIN1A — Comparator 1 positive input A.

I

KBI4 — Keyboard input 4.

O DAC1 — Digital-to-analog converter output 1.

I

AD13 — ADC1 channel 3 analog input.

I/O P0.5 — Port 0 bit 5. High current source.

I

CMPREF — Comparator reference (negative) input.

I

KBI5 — Keyboard input 5.
