When this LSI accesses external address space, it can insert an idle cycle (T
in the following three cases: (1) when read accesses in different areas occur consecutively or when
an external access cycle occurs after a single address transfer, (2) when (1) occurs and a write
cycle occurs immediately after a read cycle, and (3) when (1) and (2) occur and a read cycle
occurs immediately after a write cycle. A condition for idle cycle insertion can be selected with
the IDLE1 and IDLE0 bits in BCR. The number of idle cycles to be inserted can be set from one
to four states by setting the IDLC1 and IDLC0 bits in BCR. By inserting an idle cycle it is
possible, for example, to avoid data collisions between ROM, etc., with a long output floating
time, and high-speed memory, I/O interfaces, and so on.
