DEI interrupt request
In auto-request mode, transfer begins when NMIF, AE and TE are all and the DE
and DME bits are set to 1.
DREQ = level detection in the burst mode (external request), or cycle steal mode.
DREQ = edge detection in the burst mode (external request), or auto request mode
in burst mode.
