Enhanced Pulse Width Modulator (ePWM) Module
qualifier submodule to generate the signal as shown for EPWMxA.
• Mode 6: Bypass rising-edge-delay and Mode 7: Bypass falling-edge-delay
Finally the last two entries in Table 3-14 show combinations where either the falling-edge-delay (FED)
or rising-edge-delay (RED) blocks are bypassed.
Table 3-14. Classical Dead-Band Operating Modes
