In the data phase dma handler, mask off just the enable bits instead of clearing the whole register. Clearing the direction bit could be bad. Also don't stop a DMA until MREQPEND goes false. Doing this may cause an ABORT on the PCI bus although I have yet to see this happen. Add definitions for MREQPEND and the BRDCTL register. The BRDCTL register is used to handle high byte termination and automatic termination testing. |
