Notes: 1. In auto-request mode, transfer begins when the NMIF, AE, and TE bits are all 0 and the DE and
(SAR, DAR, DMATCR, CHCR, DMAOR, DMARS)
DMATCR – 1 → DMATCR, SAR and DAR
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)
DME bits are set to 1.
