System Controller Register Definitions

The following registers are located in the Peripheral Memory-Mapped Register (PMMR)

address space. They are accessible through the south internal bus accesses. The

Internal Bus Arbitration Control Register provides controls for both the North and South

Internal address busses. The south internal bus address and data test registers are

used to force address or data parity errors on the south internal bus respectively. Note

that the north internal bus does not support address and data parity.

• Internal Bus Arbitration Control Register

• South Internal Bus Address Test Register

• South Internal Bus Data Test Register
