P89LPC938
8-bit microcontroller with 10-bit A/D converter
[1]
Input/Output for P1.0 to P1.4, P1.6, P1.7. Input for P1.5.
P2.4/SS

I/O
P2.4 — Port 2 bit 4.
I
SS — SPI Slave select.
P2.5/SPICLK
16
12
I/O
P2.5 — Port 2 bit 5.
I/O
SPICLK — SPI clock. When congured as master, this pin is output;
when congured as slave, this pin is input.
P2.6/OCA
27
23
I/O
P2.6 — Port 2 bit 6.
O
OCA — Output Compare A.
P2.7/ICA
28
24
I/O
P2.7 — Port 2 bit 7.
I
ICA — Input Capture A.
P3.0 to P3.1
I/O
Port 3: Port 3 is a 2-bit I/O port with a user-congurable output type.
During reset Port 3 latches are congured 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 conguration selected. Each port pin is
congured independently. Refer to Section 7.13.1 “Port congurations”
and Table 10 “DC electrical characteristics” for details.
All pins have Schmitt triggered inputs.
Port 3 also provides various special functions as described below:
P3.0/XTAL2/
CLKOUT
9
5
I/O
P3.0 — Port 3 bit 0.
O
XTAL2 — Output from the oscillator amplier (when a crystal oscillator
option is selected via the Flash conguration.
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
8
4
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 conguration). 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

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