301 / 1025 page  Section 7 DMA Controller (DMAC) Rev. 3.00 Sep 15, 2006 page 267 of 988 REJ09B0330-0300 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. DMA read φ Address bus RD LWR TEND HWR Bus release Block transfer Last block transfer DMA write DMA read DMA write DMA dead DMA read DMA write DMA read DMA write DMA dead Bus release Bus release Figure 7.22 Example of Full Address Mode (Block Transfer Mode) Transfer 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. |
