13.6.2.2
The PnICR registers should be configured according to the specific interrupts, periodic and aperiodic,
required for each port. In addition, the port interrupt enable, (PnICR[IE]) should be set for each active port
prior to receiving interrupts.
Assuming port 1 is configured as in the above example then the following configuration would enable
periodic interrupts on port 1 with only the D channel active.
The programming of the P1ICR in the above example is achieved with the following ColdFire code
sequence assuming the equates and init sections as in the previous P1CR example:
...
move.w
move.w
