Section 7 DMA Controller (DMAC)
7.5.9
(1)
Figure 7.18 shows a transfer example in which TEND output is enabled and byte-size short
address mode transfer (sequential/idle/repeat mode) is performed from external 8-bit, 2-state
access space to internal I/O space.
A byte or word transfer is performed for a single transfer request, and after the transfer, the bus is
released. While the bus is released, one or more bus cycles are executed by the CPU or DTC.
In the transfer end cycle (the cycle in which the transfer counter reaches 0), a one-state DMA dead
cycle is inserted after the DMA write cycle.
In repeat mode, when TEND output is enabled, TEND output goes low in the transfer end cycle.
