Not all pins or pin functions are available on all devices, see
Port pins are software configurable with pullup device if input port.
Port pins are software configurable for output drive strength.
Port pins are software configurable for output slew rate control.
IRQ contains a software configurable (IRQPDD) pullup device if PTA5 enabled as IRQ pin function (IRQPE = 1).
RESET contains integrated pullup device if PTA5 enabled as reset pin function (RSTPE = 1).
PTA4 contains integrated pullup device if BKGD enabled (BKGDPE = 1).
SDA and SCL pin locations can be repositioned under software control (IICPS), defaults on PTA2 and PTA3.
When pin functions as KBI (KBIPEn = 1) and associated pin is configured to enable the pullup device, KBEDGn can be used to reconfigure
the pullup as a pulldown device.
