GE DS200QTBAG1ADC 电源板模块

产品详情资料

当用户设置DGCS寄存器中的STOP_REQ位时，它告诉DMA立即停止其在源总线上的操作。FIFO中的剩余数据继续写入目标总线，直到FIFO为空。一旦FIFO为空，则设置同一寄存器中的STOP位，如果启用，则生成中断。DMA寄存器将包含DMA停止的值：DTBC寄存器包含传输中剩余的字节数，源和目标地址寄存器包含下一个要读/写的地址，DCPP寄存器包含下个命令包，DCTL寄存器包含传输属性。如果VMEbus上发生读取事务，那么设置停止请求可能会受到VOFF计时器的影响。如果在DMA空闲等待VOFF到期时设置STOP_REQ位，然后重新开始读取，则该请求将保持挂起，直到VOFF定时器到期且总线已被授权。Halt提供了一种在命令包边界中断DMA的机制。相反，停止请求DMA立即中断，而暂停仅在当前命令包完成时生效。When the STOP_REQ bit in the DGCS register is set by the user, it tells the DMA to cease its operations on the source bus immediately. Remaining data in the FIFO continues to be written to the destination bus until the FIFO is empty. Once the FIFO is empty, the STOP bit in the same register is set and, if enabled, an interrupt generated. The DMA registers will contain the values that the DMA stopped at: the DTBC register contains the number of bytes remaining in the transfer, the source and destination address registers contain the next address to be read/written, the DCPP register contains the next command packet, and the DCTL register contains the transfer attributes. If read transactions are occurring on the VMEbus, then setting a stop request can be affected by the VOFF timer. If the STOP_REQ bit is set while the DMA is lying idle waiting for VOFF to expire before recommencing reads, then the request remains pending until the VOFF timer has expired and the bus has been granted. Halt provides a mechanism to interrupt the DMA at command packet boundaries. In contrast, a stop requests the DMA to be interrupted immediately, while halt takes effect only when the current command packet is complete.
