Definition:
The GPIO Interrupt Enable register controls which bits of port A/B/F are to be configured as
interrupts. A “1” written to a bit in this register will configure the bit on port A/B/F to become an
interrupt. The user must make sure that the direction of port A/B/F is set to input (PxDDR
defaults to input on reset). Writing a “0” (default on reset) to a bit in the register will configure
that bit on port A/B/F as a normal GPIO port and the interrupt output corresponding to that bit
will be zeroed. The user can read the inputs on port A/B/F in either mode via the PxDR.
The interrupt type is controlled by the GPIOxINTTYPE1/2 registers described in the following
sections.
