6.17 Enhanced Pulse Width Modulator (ePWM) Modules (ePWM1/2/3/4/5/6/7/8)
The devices contain up to eight enhanced PWM Modules (ePWM). Figure 6-42 shows a block diagram of
multiple ePWM modules. Figure 6-43 shows the signal interconnections with the ePWM.
Table 6-50 and Table 6-51 show the complete ePWM register set per module.
