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.
SDA LCD — I
SCL LCD — I
BP0 to BP3: LCD backplane outputs.
S0 to S31: LCD segment outputs.
Ground: 0 V reference.
Power supply: This is the power supply voltage for normal operation as well as Idle
and Power-down modes.
LCD power supply: LCD supply voltage.
