9054 block DMA
9054 datasheet 第四章有关block DMA传输:
The Host processor or the local processor sets the local and PCI starting address,transfer byte count,and transfer direction. The host or local processor then sets the DMA start bit to initiate a transfer. 具体怎么通过local processor 设置 DMA 传输的起始地址 字节计数和传输方向的呢?(不明白通过local processor是具体怎么操作) :) |
