P3.0 — Port 3 bit 0.
XTAL2 — Output from the oscillator amplifier (when a crystal oscillator option is
selected via the flash configuration).
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 — Port 3 bit 1.
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.
Ground: 0 V reference.
Power supply: This is the power supply voltage for normal operation as well as
Idle and Power-down modes.
