CAS Latency Control
The CAS latency is controlled by bits W21 and W20 in WTCRB. Table 6.27 lists the setting and
CAS latency. CAS latency control cycles (Tcl) are inserted in a read cycle according to the W21
and W20 settings. WTCRB can be specified regardless of bit AST2 in ASTCR.
Figure 6.62 shows a timing example when SDRAM with a CAS latency of 3 is in use.
Bits W21 and W20 is initialized to B'11.
