Write Access
The IXF1110 MAC Write access cycle operation is done in the following order:
Figure 25
UPX_DATA[31:0]
1. Chip Select (UPX_CS_L) is asserted at all times for the duration of the operation. The address
2. UPX_WR_L should be asserted by the CPU. The IXF1110 MAC latches the address.
3. The CPU drives valid data onto the processor bus (UPX_DATA[31:0]).
4. The CPU de-asserts the asynchronous Write signal (UPX_WR_L) of the IXF1110 MAC. The
5. The IXF1110 MAC assertss asynchronous-ready (UPX_RDY_L). The glue logic indicates to
