36.7.6 Sequencer n Configuration Register
Name:
SEQCFGn
Access Type: Read/Write
Offset: 0x14 + n * 0x04
Reset Value: 0x00000000
It is adviced not changing the configuration once the module is enabled. In order to do so, first turn off the module by writ-
ting a 0 in CFG.ADCEN, then change the configuration.
• CNVNB: Number of Conversions in a Sequence
The number of conversions to perform in the sequence is (CNVNB+1).
• SRES: Resolution
0: 12 bits.
1: 10 bits.
2: 8 bits.
3: Reserved.
• TRGSEL: Trigger Selection
0: Software.
1: Internal ADC timer.
2: Event controller source.
3: Continuous.
• SHDYN: Sample and Hold Dynamic Mode
1: The SH dynamic mode,is enabled, a conversion takes two ADC clock cycles, SH is reseted on the first cycle.
0: The SH dynamic mode is disabled, a conversion takes a single ADC clock cycle.
• OVSX2: Oversampling X2
1: The oversampling mode is enabled, a conversion takes two ADC clock cycles.
0: The oversampling mode is disabled, a conversion takes a single ADC clock cycle.
