D.10 Multichannel Pulse-Width Modulation (MCPWM)
MC68F375
REFERENCE MANUAL
MCPWM generates pulse-width modulated outputs with full 0% to 100% duty cycle
range independent of other TPU activity. This capability requires two TPU channels
plus an external gate for one PWM channel. (A simple one-channel PWM capability is
supported by the QOM function.)
Multiple PWMs generated by MCPWM have two types of high time alignment: edge
aligned and center aligned. Edge-aligned mode uses n + 1 TPU channels for n PWMs;
center-aligned mode uses 2n + 1 channels. Center-aligned mode allows a user-de-
fined “dead time” to be specified so that two PWMs can be used to drive an H-bridge
without destructive current spikes. This feature is important for motor control applica-
tions.
