Wake-up Function Register - PAWK
When the microcontroller enters the Sleep Mode, various methods exist to wake the device up and
continue with normal operation. One method is to allow a falling edge on the I/O pins to have a
wake-up function. This register is used to select which Port A I/O pins are used to have this wake-up
function.
Pull-high Registers - PAPU, PBPU, PCPU, PDPU
The I/O pins, if configured as inputs, can have internal pull-high resistors connected, which eliminates
the need for external pull-high resistors. This register selects which I/O pins are connected to internal
pull-high resistors.
Software COM Register - SCOMC
The pins PB6, PB7, PC6, PC7 on Port B and Port C can be used as SCOM lines to drive an external
LCD panel. To implement this function, the SCOMC register is used to setup the correct bias voltages
on these pins.
