PMC Slots Available Power

Note:

A maximum load current of 6 amps (worst case) results in a voltage drop of approximately 100 mV to the PMC 5 volt power supply inputs. To ensure proper module operation, adjust the CompactPCI power supply to accommodate any voltage drop or power supply ripple that may occur when operating the carrier card.

2To prevent ESD damage to the CC1000dm carrier card and the PMC modules, wear a grounding wriststrap and use a grounded work surface while handling the card.

3Set up the PMC module and install it on the CC1000dm carrier card as specified in the module’s hardware manual.

Monarch Functionality Each slot (PMC1 and PMC2) on the CC1000dm carrier card can be configured to func- tion as either a Monarch or non-Monarch PMC slot (in non-transparency or legacy mode), as described in the Processor PMC Standard for Processor PCI Mezzanine Cards, VITA 32- 2003 Specification. Although only one slot can be a Monarch, there can be as many non-Monarch PMCs as the carrier card can support. A module placed on the Monarch slot performs local PCI bus enumeration and handles PMC interrupts. A mod- ule placed on the non-Monarch slot behaves in the traditional slave processor manner. Both slots have the ability to be configured as either Monarch or non-Monarch by the 10-pin jumper at JP3.

IDSEL Mapping for PCI

Devices

Once the Monarch PMC module has completed initialization of the CC1000dm local bus, the PCI agents located on that bus are available for access. There are up to two PCI devices installed on the PLX PCI 6254 (HB6) secondary bus and two PCI IDSEL lines allocated to each PMC slot. Table 3-2lists all the IDSEL mappings.
