P1.0 to P1.7
I/O, I
Port 1: Port 1 is an 8-bit I/O port with a user-configurable output type, except for
three 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
details. P1.2 to 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
18
I/O
P1.0 — Port 1 bit 0.
O
TXD — Transmitter output for serial port.
P1.1/RXD
17
I/O
P1.1 — Port 1 bit 1.
I
RXD — Receiver input for serial port.
P1.2/T0/SCL
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 overflow output (open-drain when
used as output).
I/O
SCL — I2C-bus serial clock input/output.
P1.3/INT0/SDA
11
I/O
P1.3 — Port 1 bit 3 (open-drain when used as output).
I
INT0 — External interrupt 0 input.
I/O
SDA — I2C-bus serial data input/output.
P1.4/INT1
10
I/O
P1.4 — Port 1 bit 4. High current source.
I
INT1 — External interrupt 1 input.
P1.5/RST
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 ISP mode.
P1.6/OCB
5
I/O
P1.6 — Port 1 bit 6. High current source.
O
OCB — Output Compare B. (P89LPC9351/9361)
P1.7/OCC/AD00
4
I/O
P1.7 — Port 1 bit 7. High current source.
O
OCC — Output Compare C. (P89LPC9351/9361)
I
AD00 — ADC0 channel 0 analog input.
