Full Address Mode (Block Transfer Mode): Figure 7-22 shows a transfer example in which TEND output is enabled
and word-size full address mode transfer (block transfer mode) is performed from internal 16-bit, 1-state access space to
external 16-bit, 2-state access space.
A one-block transfer is performed for one transfer request, and after the transfer the bus is released. While the bus is
released, one or more bus cycles are inserted 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.
One block is transmitted without interruption. NMI generation does not affect block transfer operation.
