Each parallel I/O can be programmed to generate an interrupt when a level change
occurs. This is controlled by the PIO_IER (Interrupt Enable) and PIO_IDR (Interrupt Dis-
able) registers which enable/disable the I/O interrupt by setting/clearing the
corresponding bit in the PIO_IMR. When a change in level occurs, the corresponding bit
in the PIO_ISR (Interrupt Status) is set whether the pin is used as a PIO or a peripheral
and whether it is defined as input or output. If the corresponding interrupt in PIO_IMR
(Interrupt Mask) is enabled, the PIO interrupt is asserted.
When PIO_ISR is read, the register is automatically cleared.
Each individual I/O is associated with a bit position in the Parallel I/O user interface reg-
isters. Each of these registers are 32 bits wide. If a parallel I/O line is not defined, writing
to the corresponding bits has no effect. Undefined bits read zero.
