TMS320F280049: what would happen if using more than 4 ePWM modules?

As mentioned in the TRM, When configuring the sync chain propagation path using the SYNCSEL registers, make sure that the longest path does not exceed four ePWM modules. Could you please help address any issues if doing so? Thank you.

    It is not recommended becuase of some undefined behavior occurs if you do. I do not have a list of the undefined behavior but this is a very important requirement that should not be violated.
