Arbitration for the secondary PCI bus is provided by the PLX PCI 6254 arbiter. Table 3-5in the previous chapter shows request/grant assignments for the carrier board second- ary PCI bus.

The PCI device configuration registers are accessed by connecting the IDSEL signal of each PCI agent to an A/D signal as defined in the PCI Local Bus Specification Revision 2.3. Table 3-2in the previous chapter shows the IDSEL definitions for the CC1000dm.

The PLX PCI 6254 PCI-to-PCI bridge provides clock generation for the secondary local bus. The s_m66en signal determines whether the frequency of the secondary PCI clock is 33 MHz or 66 MHz.

The CC1000dm carrier card interface is designed to conform to the Hot Swap require- ments of the PICMG® 2.1 CompactPCI® Hot Swap Specification/Revision 2.0. This specification adds features to the standard CC1000dm carrier card interface to allow orderly insertion and extraction of boards without adversely affecting system opera- tion. This makes it easy to repair faulty boards or reconfigure a system. Hot Swap also provides programmatic access to Hot Swap services allowing system reconfiguration and fault recovery to take place with no system down time and minimum operator interaction.

Overview Hot Swap architecture is layered to address a wide range of applications with few interoperability problems. From a system standpoint, the PICMG® 2.1 CompactPCI® Hot Swap Specification Revision 2.0 defines minimum capabilities. Additional capabilities
