CHAPTER 20 EVENT LINK CONTROLLER (ELC) (RL78/F14 Only)
The event link controller (ELC) mutually connects (links) events output from each peripheral function. By linking events,
it becomes possible to coordinate operation between peripheral functions directly without going through the CPU.
20.1 Overview
The ELC has the following functions.
 Capable of directly linking event signals from 20 (Group D products) or 26 (Group E products) types of peripheral
functions to specified peripheral functions
 Event signals can be used as activation sources for operating any one of seven (Group D products) or nine (Group
E products) types of peripheral functions

flash memory or RL78/F13 (LIN incorporated) products with 80 pins and 64 Kbytes to 128 Kbytes
of code flash memory
Group C: RL78/F13 (CAN incorporated) products with 30, 32, 48, 64, or 80 pins and 32 Kbytes to 128 Kbytes
of code flash memory
Group D: RL78/F14 products with 30, 32, 48, 64, or 80 pins and 48 Kbytes to 96 Kbytes of code flash
memory
Group E: RL78/F14 products with 48, 64, or 80 pins and 128 Kbytes to 256 Kbytes of code flash memory or
RL78/F14 products with 100 pins and 64 Kbytes to 256 Kbytes of code flash memory
