The ADR and control signals (R/W_L, BW_L[7:0], CE_L, CE2, CE2_L) are sampled on a CLK edge. For Write cycles, the data
is sampled two cycles later; for Read cycles, the data is available to the processor two cycles later. Both Write- and Read-cycle
latency is two cycles and there is no gap required between Read and Write operations. Every cycle is available for the network
processor(s) for full utilization of the bus bandwidth. See Figure 9-1. Note. BWE_L is not used in this mode and should be tied
inactive.
