RPC56EL60L5

Introduction

136



Individual software control for each PWM output



All outputs can be forced to a value simultaneously



PWMX pin can optionally output a third signal from each channel



Channels not used for PWM generation can be used for buffered output compare

functions



Channels not used for PWM generation can be used for input capture functions



Enhanced dual edge capture functionality



Option to supply the source for each complementary PWM signal pair from any of the

following:

–

External digital pin

–

Internal timer channel

–

External ADC input, taking into account values set in ADC high- and low-limit

registers



DMA support

1.5.31

eTimer module

The MPC5643L provides three eTimer modules (on the LQFP package eTimer_2 is

available internally only without any external I/O access). Six 16-bit general purpose

up/down timer/counters per module are implemented with the following features:



Maximum clock frequency of 120 MHz



Individual channel capability

–

Input capture trigger

–

Output compare

–

Double buffer (to capture rising edge and falling edge)

–

Separate prescaler for each counter

–

Selectable clock source

–

0–100% pulse measurement

–

Rotation direction flag (Quad decoder mode)



Maximum count rate

–

Equals peripheral clock divided by 2 for external event counting

–

Equals peripheral clock for internal clock counting



Cascadeable counters



Programmable count modulo



Quadrature decode capabilities



Counters can share available input pins



Count once or repeatedly



Preloadable counters



Pins available as GPIO when timer functionality not in use



DMA support

1.5.32

Sine Wave Generator (SWG)

A digital-to-analog converter is available to generate a sine wave based on 32 stored values

for external devices (ex: resolver).
