P89LPC980/982/983/985
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.
P3.0/XTAL2/
CLKOUT
9I/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
8
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.

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