Chapter 7. Operation Timing (Memory Expansion and Microprocessor Modes)

7.1 Separate Bus (no wait)

Table 7.1 and Figure 7.1 show bus timing when using the memory expansion mode and micropro-
cessor mode (separate bus, no wait).

Table 7.1 Memory expansion mode and microprocessor mode (separate bus, no wait)

Note 1. Compute bus timing according to BCLK frequency. Use the below formula.

td(DB-WR) =
