Transfer Direction (Settable Memory Interface)
DTR.COUNT [7:4] (DTR [23:20]): Sets the port as
not used. In DDT mode on the SH7751, an external
device and the DMAC perform handshaking using
the DBREQ, BAVL, TR, TDACK, ID[1:0], and
D[31:0] signals during data transfer. On the
SH7751R, the DBREQ, BAVL, TR, TDACK, ID[2:0],
and D[31:0] signals are used for handshaking
during data transfer between an external device and
the DMAC.
