Notes

1.Programmable via the Raven’s PCI Configuration registers. For the MVME2300 series, RAM size is limited to 128MB.

2.To enabled the CHRP “io-hole”, program the Raven to ignore the 0x000A0000 - 0x000FFFFF address range.

3.Programmable mapping via the four PCI Slave Images in the Universe ASIC.

4.Programmable mapping via the Special Slave Image (SLSI) in the Universe ASIC.
