42.7.4 ADC Channel Sequence 2 Register
Name: ADC_SEQR2
Address: 0xF804C00C
Access: Read-write
This register can only be written if the WPEN bit is cleared in “ADC Write Protect Mode Register” on page 981.
• USCHx: User Sequence Number x
The sequence number x (USCHx) can be programmed by the Channel number CHy where y is the value written in this field. The
allowed range is 0 up to 11. So it is only possible to use the sequencer from CH0 to CH11.
This register activates only if ADC_MR(USEQ) field is set to ‘1’.
Any USCHx field is taken into account only if ADC_CHSR(CHx) register field reads logical ‘1’ else any value written in USCHx
does not add the corresponding channel in the conversion sequence.
Configuring the same value in different fields leads to multiple samples of the same channel during the conversion sequence. This
can be done consecutively, or not, according to user needs.
