Part Number: TMS320F28388D
Hello,
In the ePWM chapter the diagram called Figure 26-51. DCxEVT1 Event Triggering is missing some arrows and that makes it confusing. Is there an updated version available?
The TRM states the following:
-
In 26.11.4.1 Digital Compare Events
The DCAEVT1.sync and DCBEVT1.sync events are ORed with the EPWMxSYNCI input signal and the
TBCTL[SWFSYNC] signal to generate a synchronization pulse to the time-base counter. -
In 26.4.3.3 Time-Base Counter Synchronization
DCAEVT1 and DCBEVT1 digital compare events can be configured to generate synchronization
pulses which have the same affect as EPWMxSYNCI.
NOTE: If the EPWMxSYNCI signal is held HIGH, the sync will NOT continously occur. The
EPWMxSYNCI is rising edge activated.
So if I understand correctly the DCAEVT1.sync signal will not repeatedly trigger the synchronization if DCAEVT1 is held high. Is it correct?
Can someone confirm that not only is EPWMxSYNCI rising-edge activated but DCAEVT1.sync is rising-edge activated aswell?
Cheers,
Pierre
