Hold Times:
1. In setup and hold times, W (write) refers to either one or both byte write enables LW and UW.
2. All read and write cycle timings are referenced from CLK or CG.
3. CG is a don’t care when UW or LW is sampled low.
4. Maximum access times are guaranteed for all possible PowerPC external bus cycles.
5. This is a synchronous device. All addresses must meet the specified setup and hold times for ALL rising edges of CLK whenever TSP or
6. 5 ns of setup delay is incurred in address buffers.
TSC is low, and the chip is selected. All other synchronous inputs must meet the specified setup and hold times for ALL rising edges of
CLK when the chip is enabled. Chip enable must be valid at each rising edge of clock for the device (when TSP or TSC is low) to remain
enabled.
