D.16 Synchronized Pulse-Width Modulation (SPWM)
MPC555 / MPC556
USER’S MANUAL
The SPWM function generates a pulse-width modulated waveform (PWM). The CPU
can change the period or high time of the waveform at any time. Three different oper-
ating modes allow the function to maintain complex timing relationships between
channels without CPU intervention.
The SPWM output waveform duty cycle excludes 0% and 100%. If a PWM does not
need to maintain a time relationship to another PWM, the PWM function should be
used instead. See Motorola TPU Progamming Note
Modulation TPU Function (SPWM), (TPUPN19/D).
