Table 4-2:

Control Signals

Note:

The 66 MHz PCI operation requires 3.3 V signaling.

Both the primary (cPCI) and secondary (PMC) sides of the PCI bridge can be selected for either 3.3 volt or 5 volt signaling. Refer to the PCI Local Bus Specification, Revision 2.3 for details on these signals. All signals are bi-directional unless otherwise stated. This is described as follows:

Signal:

 

Description:

p_vio

 

PRIMARY INTERFACE I/O VOLTAGE. If a device on the primary PCI bus uses 5 volt

 

 

 

 

signaling, then p_vio is configured for 5 volt signaling. If the device uses 3.3 volt

 

 

signaling, then p_vio is configured for 3.3 volt signaling.

 

 

The primary side 3.3 V/5 V operation is controlled by the CompactPCI VIO.

 

 

 

s_vio

 

SECONDARY INTERFACE I/O VOLTAGE. If a device on the secondary PCI bus uses

 

 

5 volt signaling, then s_vio is configured for 5 volt signaling. If the device uses 3.3

 

 

volt signaling, then s_vio is configured for 3.3 volt signaling.

 

 

The secondary side 3.3 V/5 V operation is controlled by a hardware jumper on the

 

 

carrier card (refer to page 2-7).

The tables in this section list the CC1000dm backplane signals. Connectors J1 and J2 provide CompactPCI bus signals (see specification for details). The pin assignments for connectors J3 and J5 are compatible with the Motorola MCP/MCPN750 board. All sig- nals are bi-directional unless stated otherwise.
