2.3 Configurable Logic Block (CLB)

One CLB module is used to generate the symmetrical pulse from PWMH to PWML, and generate the sync event for all ePWM module to start the next switching cycle. Another CLB module is used to create the SR PWM signals for secondary FETs, which is independent to the HHC control.
