18. Event Link Controller (ELC)
Under development Preliminary document
Specifications in this document are tentative and subject to change.
(2) Event Generation by Input Single-Ports
An input single-port generates an event when the signal value of the external pin connected to the relevant port changes.
The event generation condition is specified using the PEL0 to PEL3 registers. An example of operation is shown in
(3) Output Single-Port Operation upon Event Input
When an event is input to an output single-port, the PODR value of the relevant port changes. The specific change of the
PODR value is specified using the PEL0 to PEL3 registers. Thus, the change of the PODR value changes the signal value
of the external pin connected to the relevant port. An example of operation is shown in Figure 18.3.
(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 PGCn registers. When an event is input to an
input port group, the signal value of the external pin upon event input is transferred to PDBFn. 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
(5) Output Port Group Operation upon Event Input
When an event is input to an output port group, the PODR values change to the values according to the PGCn settings.
An example of operation is shown in Figure 18.5.
