Hi expert,
My customer is using F28075 and want to use phase function. and they want to disable EXTSYNC1.
The reason is they want to use SW sync, but EXTSYNC1 will trigger it by fault.
As describe in TRM:
Software Forced Synchronization Pulse: Writing a 1 to the TBCTL[SWFSYNC] control bit invokes a software forced synchronization. This pulse is ORed with the synchronization input signal, and therefore has the same effect as a pulse on EPWMxSYNCI.
there are two ways to achieve this function:
1. EXTSYNC1 is sourced from INPUTXBAR5 and on F28075, there is must link to a GPIO, or I can write a value which will not conncet to any GPIO, then what the value is , 1 or 0?
2. Or just disable EXTSYNC1, but I did not find the description.
Could you give some suggestion on it?
BR
Emma
