See the listed chapter for information about modules that share these pins.
When an on-chip peripheral system is controlling a pin, data direction control bits still determine what is
read from port data registers even though the peripheral module controls the pin direction by controlling
the enable for the pin’s output buffer. See the
Pullup enable bits for each input pin control whether on-chip pullup devices are enabled whenever the pin
is acting as an input even if it is being controlled by an on-chip peripheral module. When the PTD7, PTD3,
PTD2, and PTG4 pins are controlled by the KBI module and are configured for rising-edge/high-level
sensitivity, the pullup enable control bits enable pulldown devices rather than pullup devices.

Alternate Function
When an alternative function is first enabled it is possible to get a spurious
edge to the module, user software should clear out any associated flags
before interrupts are enabled.
modules are enabled. The highest priority module will have control over the
pin. Selecting a higher priority pin function with a lower priority function
already enabled can cause spurious edges to the lower priority module. It is
recommended that all modules that share a pin be disabled before enabling
another module.
