A one-block 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 of each block (the cycle in which the transfer counter reaches 0), a one-
state DMA dead cycle is inserted after the DMA write cycle. Even if an NMI interrupt is
generated during data transfer, block transfer operation is not affected until data transfer for one
block has ended.
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 7.22 shows an example of normal mode transfer activated by the DREQ pin falling edge.
