... Internal DRAM access control (CS) __ The internal DRAM can be accessed when CS is driven to an "L" level after the M32000D4AFP enters the hold state (HACK = "L"). To access the internal DRAM from external, the following signals from the system bus side should be controlled. ...
Page 21
... When an "L" level is input to DC, the next bus cycle is processed and wait cycles are inserted until this point. When a write cycle comes immediately after a read cycle, the M32000D4AFP 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 ...
