DMA Handshake
These specifications describe the three DMA handshake modes.
In all three modes, DMARx is used to initiate transfers. For
Handshake mode, DMAGx controls the latching or enabling of
data externally. For External handshake mode, the data transfer
is controlled by the ADDR31–0, RD, WR, PAGE, MS3–0, ACK,
