(4) Input Port-Group Operation upon Event Input and Event Generation
An input port-group generates an event when the signal value of any one of the external pins
connected to the relevant port-group changes. The event-generation condition is specified using
the PGC1 and PGC2 registers. When an event is input to an input port-group, the signal value of
the external pin upon event input is transferred to PDBF. In this case, only the values of the bits
specified as members of the input port-group are transferred. An example of operation is shown in
figure 12.4.
(5) Output Port-Group Operation upon Event Input
When an event is input to an output port-group, the PDR values change to the values according to
the PGC1 or PGC2 settings. An example of operation is shown in figure 12.5.
