1. Overview

Event link controller (ELC)

 Event signals such as interrupt request signals can be interlinked with the operation of

functions such as timer counting, eliminating the need for intervention by the CPU to

control the functions.

 188 internal event signals can be freely combined for interlinked operation with

connected functions.

 Event signals from peripheral modules can be used to change the states of output pins

(of ports B and E).

 Changes in the states of pins (of ports B and E) being used as inputs can be interlinked

with the operation of peripheral modules.

Timers

8-bit timers (TMR)

 (8 bits × 2 channels) × 4 units

 Select from among seven internal clock signals (PCLKB/1, PCLKB/2, PCLKB/8, PCLKB/

32, PCLKB/64, PCLKB/1024, PCLKB/8192) and one external clock signal

 Capable of output of pulse trains with desired duty cycles or of PWM signals

 The 2 channels of each unit can be cascaded to create a 16-bit timer

 Generation of triggers for A/D converter conversion

 Capable of generating baud-rate clocks for SCI5, SCI6, and SCI12

 Event linking by the ELC

Compare match timer

(CMT)

 (16 bits × 2 channels) × 2 units

 Select from among four internal clock signals (PCLKB/8, PCLKB/32, PCLKB/128,

PCLKB/512)

 Event linking by the ELC

Watchdog timer (WDTA)

 14 bits × 1 channel

 Select from among 6 counter-input clock signals (PCLKB/4, PCLKB/64, PCLKB/128,

PCLKB/512, PCLKB/2048, PCLKB/8192)

Independent watchdog

timer (IWDTa)

 14 bits × 1 channel

 Counter-input clock: IWDT-dedicated on-chip oscillator

 Dedicated clock/1, dedicated clock/16, dedicated clock/32, dedicated clock/64, dedicated

clock/128, dedicated clock/256

 Window function: The positions where the window starts and ends are specifiable (the

window defines the timing with which refreshing is enabled and disabled).

 Event linking by the ELC
