ABSTRACT:
Even when an S-PCI bus1brequests transfer while a P-PCI bus1ais executing burst transfer, assert of a TRDY# signal for data transfer of the P-PCI side is delayed so that next data transfer of the P-PCI side is completed within 8 clock cycles since the TRDY# signal for data transfer of the P-PCI side is asserted.
