DTC Operation Register (DTCOR)
The DTCOR register sets the operation of the DTC module.
SQTFRL Bit (Sequence Transfer Terminate)
Setting the SQTFRL bit to 1 terminates the sequence transfer in progress.
When the DTCSQE.ESPSEL bit is 1 (Sequence transfer is enabled), follow the procedure shown in
terminate the sequence transfer.
Writing 1 to the bit, while no sequence transfer is performed, have no effect.
