Notes:
(SAR, DAR, DMATCR, CHCR, DMAOR)
DMATCR − 1 → DMATCR, SAR and DAR
1. In auto-request mode, transfer begins when AE, NMIF and TE are both 0 and the DE and DME
2. DREQ = level detection in burst mode (external request) or cycle-steal mode.
3. DREQ = edge detection in burst mode (external request), or auto-request mode in burst mode.
DEI interrupt request (when IE = 1)
bits are set to 1.
