14.8.4
In DDT mode, the request queues of any channel can be cleared by using DTR.ID, DTR.MD,
DTR.SZ, and DTR.COUNT [7:4] in a DTR format. This function is only available when
DMAOR.DBL = 1. Table 14.17 shows the DTR format settings for clearing request queues.

DMAOR.DBL DTR.ID
Note: (SH7750R) DTR.SZ = DTR[63:61], DTR.ID = DTR[59:58], DTR.MD = DTR[57:56],
14.8.5
When the number of transfers specified in DMATCR has been finished and the interrupt request is
enabled (CHCR.IE = 1), a transfer-end interrupt request can be sent to the CPU from each
channel. Table 14.18 lists the interrupt-request codes that are associated with these transfer-end
interrupts.
