Section 10 DMA Controller (DMAC)
(2)
In single address mode, data of one byte, one word, or one longword is transferred at a single
transfer request and after the transfer the bus is released temporarily. One bus cycle or more by the
CPU or DTC are executed in the bus released cycles.
In figure 10.35, the TEND signal output is enabled and data is transferred in bytes from the
external 8-bit 2-state access space to the external device in single address mode (write).
