产品详情资料
通过在DGCS寄存器中设置halt_REQ位,请求DMA暂停。这使DMA完成由DMA寄存器的当前内容定义的传输,如果设置了CHAIN位,则加载下一个命令包。然后,DMA终止,DGCS寄存器中的HALT位被设置,如果启用,则产生中断。停止或停止后,DMA可以通过设置GO位从停止点重新启动;但在重新启动之前,必须清除STOP和HALT位。无论DMA如何停止(无论是正常、总线错误还是用户中断),DMA都将在DGCS寄存器中指示其停止的原因。STOP和HALT位被设置为响应停止或停止请求。当DMA成功完成DMA传输时,DONE位被设置,如果在该模式下运行,则包括链接列表中的所有条目。还有三个位是根据错误条件设置的:在PCI总线上遇到目标中止的情况下为LERR;VMEbus上遇到总线错误时的VERR;如果DMA未正确编程(DMA启动时PCI_CSR寄存器中的BM位未启用,或者DLA和DVA寄存器未64位对齐),则为P_ERR。在DMA重新启动之前,必须清除这些状态位中的每一个。当DMA终止时,可能会对VMEbus或PCI总线产生中断。A halt is requested of the DMA by setting the HALT_REQ bit in the DGCS register. This causes the DMA to complete the transfers defined by the current contents of the DMA registers and, if the CHAIN bit is set, load in the next command packet. The DMA then terminates, the HALT bit in the DGCS register is set, and, if enabled, an interrupt generated.After a stop or halt, the DMA can be restarted from the point it left off by setting the GO bit; but before it can be re-started, the STOP and HALT bits must both be cleared. Regardless of how the DMA stops—whether normal, bus error or user interrupted— the DMA will indicate in the DGCS register why it stopped. The STOP and HALT bits get set in response to a stop or halt request. The DONE bit gets set when the DMA has successfully completed the DMA transfer, including all entries in the linked-list if operating in that mode. There are also three bits that are set in response to error conditions: LERR in the case of Target-Abort encountered on the PCI bus; VERR in the case of a bus error encountered on the VMEbus; and P_ERR in the case that the DMA has not been properly programmed (the DMA was started with the BM bit in the PCI_CSR register not enabled, or the DLA and DVA registers were not 64-bit aligned. Before the DMA can be restarted, each of these status bits must be cleared. When the DMA terminates, an interrupt may be generated to VMEbus or PCI bus.
