Functional Description
The CPU interface is designed for a generic 32-bit asynchronous CPU bus. The bus is a 32-bit data
bus only and has an 11-bit address bus.
The IXF1110 MAC external CPU interface is asynchronous and has no clock. This allows
flexibility for CPU selection.The interface to all IXF1110 MAC registers is synchronous to 125
MHz internally.
In some applications, synchronous-to-asynchronous glue logic is required between the IXF1110
MAC and the system CPU. This glue logic must be designed so that the IXF1110 MAC Read and
Write access times are not violated. It may be possible to interface without glue logic if the CPU
can meet the timing seen in

UPX_ADD[10:0]
Internal IXF1110 MAC registers and counters are selected using the 11-bit address bus input
provided at the CPU interface. This address must be stable for the entire cycle.
