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 should not be driven above V
DD
.
4. Pin contains integrated pullup device.
5. Pins PTD7, PTD3, PTD2, and PTG4 contain both pullup and pulldown devices.
Pulldown enabled when KBI is enabled (KBIPEn = 1) and rising edge is selected
(KBEDGn = 1).
