P1.0 to P1.7
I/O, I [1] 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 8.12.1 “Port congurations”
and Table 8 “DC electrical characteristics” for details. P1.2 - P1.3 are 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:
12
I/O
P1.0 — Port 1 bit 0.
O
TXD — Transmitter output for the serial port.
11
I/O
P1.1 — Port 1 bit 1.
I
RXD — Receiver input for the serial port.
10
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.
9
I/O
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.
8
I/O
P1.4 — Port 1 bit 4. High current source (P89LPC9221).
I
INT1 — External interrupt 1 input.
4I
P1.5 — Port 1 bit 5 (input only).
I
RST — External Reset input (if selected via FLASH conguration). 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. 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.
3
I/O
P1.6 — Port 1 bit 6. High current source (P89LPC9221).
2
I/O
P1.7 — Port 1 bit 7. High current source (P89LPC9221).
