Enhanced PWM Modules (ePWM1/2/3/4)

The devices contain up to four enhanced PWM Modules (ePWM). Figure 9-35 shows a block diagram of multiple ePWM modules. Figure 9-36 shows the signal interconnections with the ePWM. For more details, see the Enhanced Pulse Width Modulator (ePWM) chapter in the TMS320F2802x,TMS320F2802xx Technical Reference Manual.

Table 9-27 shows the complete ePWM register set per module.
