Abstract
A DMA controller capable of conditional action under the control of a status register, prespecified parameters, and a condition field of the channel command, and a DMA controller which returns status information to command entry locations that are reserved for this purpose are disclosed. The prespecified parameters may be held in a register having a mask field and a value field, and a test for conditional action may be a masked comparison of the status register and the value field. The condition field determines how the test result is interpreted and allows suppressing or forcing the conditional action during a command.
