Access:
• TRGMOD: Trigger Mode
• TRGPER: Trigger Period
Effective only if TRGMOD defines a Periodic Trigger.
Defines the periodic trigger period, with the following equation:
The minimum time between 2 consecutive trigger events must be strictly greater than the duration time of the longest con-
version sequence according to configuration of registers ADC_MR, ADC_CHSR, ADC_SEQR1, ADC_SEQR2.
