The following sections describe the memory maps for the MVME2100.
The Processor Memory Map is controlled by the Processor Peripheral
device. The MPC8240 supports two address maps designated address
Map A (PReP) and address Map B (CHRP). The MVME2100 defaults to
address Map A when power is first applied or after a hard reset has
occurred.
When power is first applied or a hard reset has occurred the CPU board
defaults to address Map A or the PReP memory map as shown in the
following table.
