Figure 14.52 Single Address Mode/Burst Mode/External Device → External Bus Data
Initial settings for channel 0 demand transfer must be DTR.ID = 00 and DTR.MD = 01, 10, or
11. In this case, only single address mode can be set for channel 0.
If a setting of DTR.ID = 01, 10, or 11 is made, DTR.MD will be ignored.
a. The handshake protocol using the data bus can be executed only on channel 0. (Set
DTR.ID = 00, DTR.MD = 00, DTR.SZ ≠ 101 or 110. Operation is not guaranteed if
settings of DTR.ID = 00, DTR.MD = 00, and DTR.SZ = 101 or 110 are made.)
