The CAS Access Wait Added (CAWA) field in the DRAM Bank 2 and 3 Programmable Wait
Control Registers (DWnCON, n=2,3) adjusts the number of wait cycles automatically added to
the CAS assertion time during access to bank n. The range is from 0 (no wait cycles added) to
3.
Figure 11.24 shows the read and write timings for a setting of 2.
