Chapter 5 TIMER

Preliminary

TIMER

The TIMER module contains the following features:

•

Two periodic timers with variable intervals

•

A PWM timer with variable interval / pulse width (PWM = pulse width modulation)

5.1

PWM Timer

The PWM timer contains a 16 bit counter. The TIMER module sends an interrupt, when the counter

reaches a programmable compare value. In addition an interrupt can be sent on the overflow of the counter, if

the bit 23 (MPWM) of IMASKR in the Interrupt Controller is set. The PWM counter starts after the bit 15

(PWM) of IMASKR in the Interrupt Controller is set. Setting bit 15 of IMASKR to 0 will clear the PWM

Counter.
