This register can only be written if the WPEN bit is cleared in
• CMPMODE: Comparison Mode
• CMPSEL: Comparison Selected Channel
If CMPALL = 0: CMPSEL indicates which channel has to be compared.
If CMPALL = 1: No effect.
• CMPALL: Compare All Channels
0 = Only channel indicated in CMPSEL field is compared.
1 = All channels are compared.
• TAG: TAG of ADC_LDCR register
0 = set CHNB to zero in ADC_LDCR.
1 = append the channel number to the conversion result in ADC_LDCR register.
