11.3.3.3 Continuous Page Mode
Continuous page mode (DACRn[PM] = 11) is a type of page mode that balances
performance, complexity, and size. In typical page-mode implementations, sequential
addresses are checked for multiple hits in a DRAM block. On a hit, RAS remains asserted
and CAS is asserted with the new column address. On a miss, RAS must be precharged
again before the bus cycle begins.
Continuous page mode supports page-mode operation without requiring an address holding
register per memory block and eliminates the delay for a miss-to-precharge RAS for the
upcoming bus cycle. Because the internal MCF5307 address bus is pipelined, addresses for
