9.9.6 Enhanced PWM Modules (ePWM1/2/3/4)
The devices contain up to four enhanced PWM Modules (ePWM). 图 9-35 shows a block diagram of multiple
ePWM modules. 图 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.
表9-27 shows the complete ePWM register set per module.
