Table 20-3 shows the relationship between the transfer sources and destinations (√: Transfer enabled, ×: Transfer
Caution The operation is not guaranteed for combinations of transfer destination and source marked with
Single transfer is supported as the transfer mode.
In single transfer mode, the bus is released at each byte/halfword transfer. If there is a subsequent DMA transfer
DMA0 transfer request
When a DMA0 transfer request is acknowledged, a DMA transfer is performed and bus mastership is
released to the CPU. This operation is repeated as long as DMA0 transfer is requested, until the TC0 bit is
set to 1 (completion of DMA transfer).
Note The CPU is using the bus, or the bus is unused.
