When the DMS bit or bits DSEL4 to DSEL0 in the DMiSL register are changed, the DMAS bit in the
DMiCON sometimes becomes 1 (DMA requested) (i = 0 to 3). Therefore, set the DMAS bit to 0 (DMA not
requested) after the DMS bit or bits DSEL4 to DSEL0 in the DMiSL register are changed. Refer to 14.13
"Notes on Interrupts" for more details.
