Wait cycle insertion for the SRAM interface can be controlled by CSnWCR. If the IW bits for
each area in CSnWCR is not 0, a software wait is inserted in accordance with the wait-control bits.
For details, see section 11.4.4, CSn Wait Control Register (CSnWCR).
A specified number of Tw cycles is inserted as wait cycles in accordance with the CSnWCR
setting. The insertion timing of the wait cycle is shown in figure 11.9.
