In a DRAM space access following a normal space access, the settings of bits ICIS2, ICIS1,
ICIS0, and IDLC in BCR are valid. However, in the case of consecutive reads in different areas,
for example, if the second read is a full access to DRAM space, only a T
T
In burst access in RAS down mode, the settings of bits ICIS2, ICIS1, ICIS0, and IDLC are valid
and an idle cycle is inserted. The timing in this case is illustrated in figures 6.82 and 6.83.
