Because of the interrupt, the processor performs a DMA read operation, which also resets the interrupt latch. Sufficient priority must be assigned to the DMA channel to ensure that the DMA request is serviced before the completion of the next conversion. MICROPROCESSOR/ USER SYSTEM AD0 TO AD15...
During a short-circuit fault, the device enters a low current consumption state and an interrupt flag is set. The device can be restart at any time after receiving a short-circuit fault by simply rewriting nSTBY = 1. It then repeats another complete soft start sequence. Note that the ...
FIG. 8(d) is a detailed diagram illustrating an exemplary embodiment of the local network reception circuit76of FIG. 7. The basic responsibility of this circuit is to buffer packets terminating in the router. As shown in FIG. 8(d), there are twelve reception FIFOs95, one high-priority an...
diagram is a �nite representation of a �xed num ber of pro cesses. It has the expressiv e p ow er equiv alen t to non-deterministic �nite automaton. An interrupt is a go o d example of re�ective op eration. Interrupts cannot b e describ ed in the normal lev el alone...
A combined serial priority and parallel priority apparatus and method of operation for use in data processing systems. Each of the parallel priority circuits are interconnected by a common parallel pr
Specialized controls 405, 406, 407, 408 and capabilities are incorporated to permit rapid task switching and retention of program state information at each of the PMEs' interrupt execution levels. Such capabili
If a system can not support unscaled overlays, perhaps because of bandwidth issues or memory issues, this mechanism is not desirable. It is not rejected, but becomes a lower priority alternative. For example, if the scaling factor is below 0.1, then the normal bar can be drawn and it will...
The present application claims priority and is a continuation of co-pending Ser. No. 07/887,512, filed on May 22, 1982, now abandoned which is a continuation-in-part of the following related co-pending Patent applications: U.S. patent application Ser. No. 611,594, filed Nov. 13, 199...
Each register has a unique processor ID, the size and speed of local and global SRAMs, a processor boot mode (to boot from SRAM, PROM, or communication ports), the capability to reset and interrupt the direction and status of the six communication ports, and ASM-M port access and ...
