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,
ADC_TSMR.
When TRGMOD is set to pen detect trigger (i.e. 100) and averaging is used (i.e. bitfield TSAV differs from 0 in ADC_TSMR
register) only 1 measure is performed. Thus, XRDY, YRDY, PRDY, DRDY will not rise on pen contact trigger. To achieve
measurement, several triggers must be provided either by software or by setting the TRGMOD on continuous trigger (i.e.
110) until flags rise.
