Section 7 DMA Controller (DMAC)
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.
DREQ Pin Falling Edge Activation Timing: Set the DTA bit in DMABCRH to 1 for the channel
for which the DREQ pin is selected.
Figure 7.30 shows an example of single address mode transfer activated by the DREQ pin falling
edge.
