4.2 Enhanced PWM Modules (ePWM1/2/3/4/5/6)
The 280x device contains up to six enhanced PWM Modules (ePWM). Figure 4-3 shows a block diagram
of multiple ePWM modules. Figure 4-4 shows the signal interconnections with the ePWM. See the
TMS320x280x Enhanced Pulse Width Modulator (ePWM) Module Reference Guide (literature number
SPRU791) for more details.
