P89LPC970/971/972
8-bit microcontroller with accelerated two-clock 80C51 core
[1]
Input/output for P1.0 to P1.4, P1.6, P1.7. Input for P1.5.
P1.7/T3EX/MOSI
2
I/O
P1.7 — Port 1 bit 7. High current source.
I
T3EX — Timer/counter 3 external capture input.
I/O
MOSI — SPI master out slave in. When configured as master, this pin is output;
when configured as slave, this pin is input (pin remap).
P3.0 to P3.1
I/O
Port 3: Port 3 is a 2-bit I/O port with a user-configurable output type. During reset
Port 3 latches are configured in the input-only mode with the internal pull-up
disabled. The operation of Port 3 pins as inputs and outputs depends upon the port
configuration selected. Each port pin is configured independently. Refer to Section
All pins have Schmitt trigger inputs.
Port 3 also provides various special functions as described below:
P3.0/XTAL2/
CLKOUT
7I/O
P3.0 — Port 3 bit 0.
O
XTAL2 — Output from the oscillator amplifier (when a crystal oscillator option is
selected via the flash configuration.
O
CLKOUT — CPU clock divided by 2 when enabled via SFR bit (ENCLK -TRIM.6).
It can be used if the CPU clock is the internal RC oscillator, watchdog oscillator or
external clock input, except when XTAL1/XTAL2 are used to generate clock source
for the RTC/system timer.
P3.1/XTAL1
6
I/O
P3.1 — Port 3 bit 1.
I
XTAL1 — Input to the oscillator circuit and internal clock generator circuits (when
selected via the flash configuration). It can be a port pin if internal RC oscillator or
watchdog oscillator is used as the CPU clock source, and if XTAL1/XTAL2 are not
used to generate the clock for the RTC/system timer.
VSS
5I
Ground: 0 V reference.

I
Power supply: This is the power supply voltage for normal operation as well as
Idle and Power-down modes.
