the ACM module on SC58x is same as that of BF50x with two changes listed below:
1. The ACM_CTL.EPS bit in SC58x is used to choose between SPORT0A and SPORT0B unlike BF60x where it was used to select between SPORT2/SPORT3.
2. SC58x ACM has only three triggers to trigger an ACM event. The trigger source is selected by programming the TRGSEL field in the ACM_CTL MMR.
a. 00 - PC12(any edge on the PC12 pin will generate an ACM event)
b. 01 - Reserved
c. 10 - Trigger from TRU
d. 11- Trigger from TRU
