32KIN
32kHz Crystal Input. Connect an external, 32kHz watch crystal between 32KIN and
32KOUT as the low-frequency system clock. Alternatively, 32KIN is the input for an
external, 32kHz clock source when 32KOUT is floating.

32KOUT
32kHz Crystal Output/Input. Connect an external, 32kHz watch crystal between
32KIN and 32KOUT as the low-frequency system clock. Alternatively, float 32KOUT
when an external, 32kHz clock source is connected to the 32KIN pin.
General-Purpose, 8-Bit, Digital, I/O, Type-C Port; LCD Segment-Driver Output.
These port pins function as both bidirectional I/O pins and LCD segment-drive
outputs. All port pins are defaulted as input with weak pullup after a reset. Enabling
a pin’s LCD function disables the general-purpose I/O on the pin. Setting the PCF1
bit enables the LCD for all pins on this port and disables the general-purpose I/O
function on all pins.
