Wait State Control: Wait state insertion on the SRAM interface can be controlled by the WCR2
settings. If the WCR2 wait specification bits corresponding to a particular area are not zero, a
software wait is inserted in accordance with that specification. For details, see section 13.2.6, Wait
Control Register 2 (WCR2).
The specified number of Tw cycles are inserted as wait cycles using the SRAM interface wait
timing shown in figure 13.10.
