Section 6 Bus Controller (BSC)
Idle Cycle in Case of DRAM Space Access after Normal Space Access: 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
timing in this case is shown in figure 6.48.
