45.7.4 AFEC Channel Sequence 1 Register
Name: AFEC_SEQ1R
Address: 0x400B000C (0), 0x400B400C (1)
Access: Read/Write
This register can only be written if the WPEN bit is cleared in the AFEC Write Protection Mode Register.
 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 15. So it is only possible to use the sequencer from CH0 to CH15.
This register activates only if AFEC_MR.USEQ bit is set to ‘1’.
Any USCHx field is taken into account only if the AFEC_CHSR.CHx bit 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.
