KBI7 — Keyboard input 7.

I/O, I Port 1: Port 1 is an 8-bit I/O port with a user-conﬁgurable output type, except for three

[1]

pins as noted below. 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 7.13.1 “Port

conﬁgurations” and Table 11 “Static electrical characteristics” for details. P1.2 and P1.3

are open drain when used as outputs. P1.5 is input only.

All pins have Schmitt trigger inputs.

Port 1 also provides various special functions as described below:

P1.0/TXD

I/O

P1.0 — Port 1 bit 0.

TXD — Transmitter output for the serial port.

P1.1 — Port 1 bit 1.

P1.1/RXD

P1.2/T0/SCL

I/O

RXD — Receiver input for the serial port.

P1.2 — Port 1 bit 2 (open-drain when used as output).

I/O

T0 — Timer/counter 0 external count input or overﬂow output (open-drain when used

as output).

I/O

SCL — I²C-bus serial clock input/output.

P1.3 — Port 1 bit 3 (open-drain when used as output).

INT0 — External interrupt 0 input.

SDA — I²C-bus serial data input/output.

P1.4 — Port 1 bit 4.

P1.3/INTO/

SDA

I/O

P1.4/INT1

INT1 — External interrupt 1 input.
