Abstract

An EISA-compatible computer system having an arbitration mechanism which incorporates a programmable hold delay register and counter for delaying a CPU hold request (DHOLD) by a programmable number of BCLK cycles after an EISA device wins the top level and CPU/EISA level arbitration. The CPU hold request is not delayed if a DMA/ISA device wins the arbitration.
