MPC184 PCI Mode Hardware Reference Manual
PRELIMINARY—SUBJECT TO CHANGE WITHOUT NOTICE
Pin Assignments
3 Pin Assignments
Table 1 shows the pin connections for the MPC184 in 32 bit PCI mode. The shaded regions show the pins
that MUST be No Connected in 32b PCI mode or must be taken into special consideration for easy
migration from the MPC190.
4 Signal Descriptions
Table 2 shows the signal descriptions for the MPC184 in 32 bit PCI mode. The shaded regions show the pins
that MUST be No Connected in 32b PCI mode or must be taken into special consideration for easy
migration from the MPC190. Please also reference Chapter 2, 4 and 7 of the PCI Local Bus Specication
Revision 2.2 for other PCI system considerations.
