Pci Idsel Definition; Table 7-7 Idsel And Interrupt Mapping For Pci Devices - Emerson MVME3100 Series Installation And Use Manual

Programming Details
switch is ON, block B is mapped to the highest address as shown below. The MAP_SEL bit in the
Flash Control/Status register can override the switch and restore the memory map to the
normal configuration with block A selected. Upon RESET, this mapping reverts to the switch
selection.

7.11 PCI IDSEL Definition

Each PCI device has an associated address line connected via a resistor to its IDSEL pin for
configuration space accesses. The following table shows the IDSEL assignments for the PCI
devices and slots on each of the PCI buses on the board, along with the corresponding interrupt
assignment to the PIC external interrupt pins. Refer to the MPC8540 Reference Manual and
PCI6520CB Data Book and for details on generating configuration cycles on each of the PCI
busses.
