• Normal space access after a continuous synchronous DRAM space write access
Table 6.11 shows whether there is an idle cycle insertion or not in the case of mixed accesses to
normal space and DRAM space/continuous synchronous DRAM space.
Figure 6.80 Example of Idle Cycle Operation after Continuous Synchronous DRAM Space
If a normal space read cycle occurs after a continuous synchronous DRAM space write access
while the ICIS2 bit is set to 1 in BCR, idle cycle is inserted at the start of the read cycle. The
number of states of the idle cycle to be inserted is in accordance with the setting of bit IDLC.
It is not in accordance with the DRMI bit in DRACCR.
Figure 6.80 shows an example of idle cycle operation when the ICIS2 bit is set to 1.
