Write after Read: If an external write occurs after an external read while the ICIS0 bit in BCRH
is set to 1, an idle cycle is inserted at the start of the write cycle.
Figure 7.28 shows an example of the operation in this case. In this example, bus cycle A is a read
cycle from ROM with a long output floating time, and bus cycle B is a CPU write cycle. In (a), an
idle cycle is not inserted, and a collision occurs in cycle B between the read data from ROM and
the CPU write data. In (b), an idle cycle is inserted, and a data collision is prevented.
