While the ICIS2 bit is set to 1 in BCR and a normal space read access occurs after DRAM
space write access, idle cycle is inserted in the first read cycle. The number of states of the idle
cycle to be inserted is in accordance with the setting of the IDLC bit. It does not depend on the
DRMI bit in DRACCR. Figure 6.53 shows an example of idle cycle operation when the ICIS2
bit is set to 1.
