Previous Access
Note:
Setting the DRMI bit in DRACCR to 1 enables an idle cycle to be inserted in the case of
consecutive read and write operations in DRAM/continuous synchronous DRAM space burst
access. Figures 6.81 and 6.82 show an example of the timing for idle cycle insertion in the case of
consecutive read and write accesses to DRAM/continuous synchronous DRAM space.
