Notes

1.For a complete description of the register bits, refer to the appropriate data sheet for the specific chip. For a more detailed memory map refer to the detailed peripheral device memory maps in the MVME197LE, MVME197DP, and MVME197SP Single Board Computers Programmer’s Reference Guide.

2.Address is the physical address going to the device. It is after the BusSwitch translation from the MC88110 address to the device seen address.
