Notes
1.
The selected configuration settings are indicated by dark cell outlines.
2.
External arbitration is required.
3.
e500 core does not boot until configured by an external master.
4.
Dependent on PCI/PCI-X mode configuration.
5.
Required to meet 2 ns hold time requirement.
6.
Meets 0.7 ns hold time requirement.
7.
Local bus LAD[0:31] is sampled during POR, but only LAD[28:31] are configurable by resistor
option. Software can use this value to inform the firmware or operating system about initial board
configuration.
