6.3 Read/write operations
When a write cycle comes immediately after a read cycle, the M32000D3FP inserts an idle cycle to prevent
a collision with data on the system bus. The same applies to write cycles (burst write access) immediately
after a burst read cycle.

Note: "Hi-z" means high-impedance, and
indicates sampling timing.
Keep DC signal at the "H" level during idle cycles.
