Port 1: Port 1 is an 8-bit I/O port with a user-congurable output type, except for
three pins as noted below. During reset Port 1 latches are congured in the input only
mode with the internal pull-up disabled. The operation of the congurable Port 1 pins
as inputs and outputs depends upon the port conguration selected. Each of the
congurable port pins are programmed independently. Refer to Section 8.11.1 “Port
open drain when used as outputs. P1.5 is input only.
All pins have Schmitt triggered inputs.
Port 1 also provides various special functions as described below:
18
I/O
P1.0 — Port 1 bit 0.
O
TxD — Transmitter output for the serial port.
17
I/O
P1.1 — Port 1 bit 1.
I
RXD — Receiver input for the serial port.
12
I/O
P1.2 — Port 1 bit 2 (open-drain when used as output).
I/O
T0 — Timer/counter 0 external count input or overow output (open-drain when used
as output).
I/O
SCL — I2C serial clock input/output.
11
I
P1.3 — Port 1 bit 3 (open-drain when used as output).
I
INT0 — External interrupt 0 input.
I/O
SDA — I2C serial data input/output.
10
I
P1.4 — Port 1 bit 4.
I
INT1 — External interrupt 1 input.
6I
P1.5 — Port 1 bit 5 (input only).
I
RST — External Reset input during Power-on or if selected via UCFG1. When
functioning as a reset input a LOW on this pin resets the microcontroller, causing I/O
ports and peripherals to take on their default states, and the processor begins
execution at address 0. Also used during a power-on sequence to force In-System
Programming mode. When using an oscillator frequency above 12 MHz, the
reset input function of P1.5 must be enabled. An external circuit is required to
hold the device in reset at power-up until VDD has reached its specied level.
When system power is removed VDD will fall below the minimum specied
operating voltage. When using an oscillator frequency above 12 MHz, in some
applications, an external brownout detect circuit may be required to hold the
device in reset when VDD falls below the minimum specied operating voltage.
5
I/O
P1.6 — Port 1 bit 6.
4
I/O
P1.7 — Port 1 bit 7.
