Section 12 Event Link Controller
The event link controller (ELC) connects the events generated by the various peripheral modules
to different modules. This function allows direct cooperation between the modules without CPU
intervention. A block diagram of the ELC is shown in figure 12.1.
12.1 Overview
• Fifty-seven event signals can be directly connected to modules.
• The operation of timer modules can be selected when an event is input to the timer module.
• Events can be connected to ports 3 and 6.
Single port-pin: An event link can be set for a single specific pin of a port.
Port group: An event link can be set for a specific group of bits within an 8-bit port.
In addition, in the specified single pin or group within a port, an event is generated by a change
in the value of the linked signals.
• Four channels of events can be generated in arbitrary setting interval using the event-
generation timer.
