Figure 8. Automatic Connection Sequencing Mode 2
The protocol described above is identical to the PCI REQ/GNT protocol used by PCI bus masters, which also
must wait for bus idle through PCI FRAME and IRDY before initiating a PCI cycle. If the HPC3130 is connected
to PCI FRAME and IRDY, the HPC3130 arbitrates for the bus; although it does not drive the PCI bus or assert
FRAME to start a cycle.
There are some issues with this implementation such as bus parking and additional loading on the PCI FRAME
and IRDY signals, which need to be considered when designing a system. The system designer may have a
level of confidence that PCI adapter cards can tolerate connection to a non-idle bus. In the scenario where the
HPC3130 is not connected to the bus, then the FRAME, IRDY, and IDLEGNT must be wired to valid logic levels
and the automatic sequencing will start without any relationship to the bus.
