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/pulldown device if PTA5 enabled as IRQ pin function (IRQPE = 1).
RESET contains integrated pullup device if PTA5 enabled as reset pin function (RSTPE = 1).
PTA5 does not contain a clamp diode to V
internal pullup is enabled may be as low as V
PTA4 contains integrated pullup device if BKGD enabled (BKGDPE = 1).
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.
