Wait cycle insertion on a normal space access can be controlled by the settings of bits WR3 to
WR0 in CSnWCR. It is possible for areas 1, 4, 5, and 7 to insert wait cycles independently in read
access and in write access. Areas 0, 2, 3, and 6 have common access wait for read cycle and write
cycle. The specified number of Tw cycles are inserted as wait cycles in a normal space access
shown in figure 9.8.
