In burst access in RAS down mode, the settings of bits ICIS2, ICIS1, ICIS0, and IDLC are valid
and an idle cycle is inserted. However, in read access, note that the timings of DQMU and DQML
differ according to the settings of the IDLC bit. The timing in this case is illustrated in figures 6.85
and 6.86. In write access, DQMU and DQML are not in accordance with the settings of the IDLC
bit. The timing in this case is illustrated in figure 6.87.
