



0: Clears CHNB in AFEC_LDCR

1: Appends the channel number to the conversion result in AFEC_LDCR



0: Multiple triggers are required to get an averaged result

1: Only a Single Trigger is required to get an averaged value



Note: If conversion results are signed and resolution is below 16-bit, the sign is extended up to the bit 15 (for example, 0xF43 for 12-bit 

resolution will be read as 0xFF43 and 0x467 will be read as 0x0467). See 

3

OSR16
