4.5 Enhanced PWM Modules (ePWM1/2/3/4)
The devices contain up to four enhanced PWM Modules (ePWM). Figure 4-8 shows a block diagram of
multiple ePWM modules. Figure 4-9 shows the signal interconnections with the ePWM. See the
TMS320x2802x, 2803x Piccolo Enhanced Pulse Width Modulator (ePWM) Module Reference Guide
(literature number SPRUGE9) for more details.
Table 4-7 shows the complete ePWM register set per module.
