as the IRQ input and is set to detect rising edges, the pullup enable control bit enables a pulldown device
rather than a pullup device.

The 48-pin QFN package has two V
and V
Pin contains integrated pullup.
IRQPE must be set to enable IRQ function.
IRQ does not have a clamp diode to V
not be driven above V
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.
