2.3.6 Signal Properties Summary

Table 2-2 summarizes I/O pin characteristics. These characteristics are determined by the way the

common pin interfaces are hardwired to internal circuits.

The 48-pin QFN package has two VSS pins â VSS1

and VSS2.

Pin contains integrated pullup.

IRQPE must be set to enable IRQ function.

IRQ does not have a clamp diode to VDD. IRQ should

not be driven above VDD.

Pullup/pulldown active when IRQ pin function

enabled. Pullup forced on when IRQ enabled for

falling edges; pulldown forced on when IRQ enabled

for rising edges.

Pullup/pulldown active when KBI pin function

enabled. Pullup forced on when KBI1Px enabled for

falling edges; pulldown forced on when KBI1Px

enabled for rising edges.

When pin is configured for SCI function, pin is

configured for partial output drive.
