NOTES:
1. Port pins are software configurable with pullup device if input port.
2. Pin contains software configurable pullup/pulldown device if IRQ is enabled
(IRQPE = 1). Pulldown is enabled if rising edge detect is selected (IRQEDG = 1)
3. IRQ does not have a clamp diode to V
DD
. IRQ must not be driven above V
DD
.
4. Pin contains integrated pullup device.
5. 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.
