Type Description

P0.1 to P0.5,

P0.7

I/O

Port 0: Port 0 is an 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 8.12.1 “Port

configurations” and Table 12 “Static characteristics” for 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:

P0.1/KBI1/ 4

AD10

CLKOUT

I/O

P0.7 — Port 0 bit 7.

I/O

T1 — Timer/counter 1 external count input or overflow/PWM output.

I

CLKOUT — Clock output.

P1.2, P1.5

I/O

Port 1: Port 1 is an I/O port with a user-configurable output type. During reset Port 1

latches are configured in the input-only mode with the internal pull-up disabled. The

operation of the configurable Port 1 pins as inputs and outputs depends upon the

port configuration selected. Each of the configurable port pins are programmed

independently. Refer to Section 8.12.1 “Port configurations” and Table 12 “Static

characteristics” for details. P1.5 is input-only.

All pins have Schmitt triggered inputs.

Port 1 also provides various special functions as described below:

P1.2/T0

5

I/O

P1.2 — Port 1 bit 2.

I/O

T0 — Timer/counter 0 external count input or overflow/PWM output.
