2. C C Library 51 3 After the A D conversion is started the A D converted data is stored in the FIFO of PCI controller Each bus mastering data transfer continually tests if any data in the FIFO and then blocks transfer the system will continuously loop until the conditions are satisfied again but will not exit the block transfer cycle if the block count is not complete lf there is momentarily no A D data the PCI 9112 will relinquish the bus temporarily but returns immediately when more A D samples appear This operation continues until the whole block is done 4 This operation proceeds transparently until the PCI controller transfer byte count is complete All normal PCI bus operation applies here such as a receiver which cannot accept the transfers higher priority devices requesting the PCI bus etc Remember that only one PCI initiator can have bus mastership at any one time However review the PCI priority and fairness rules Also study the effects of the Latency Timer And be aware that the PCI priority strategy round robin rotated fixed priority custom etc is unique to your host PC and is explicitly not defined by the PCI standard You must determine this priority scheme for your own PC or replace it 5 The interrupt request from the PCI controller can be optionally set up to indicate that this longword count is complete although this can also be determined by polling the PCI controller Syntax Visual C Windows
