The 'C6211/C6711 uses a mode register value of either 0032h or 0022h. The
register value and description are shown in Figure 9–19 and Figure 9–20.
Both values program a default burst length of four words for both reads and
writes. The value actually used depends on the CASL parameter defined in the
SDRAM extension register. If the CAS latency is three, 0032h is written. If the
CAS latency is two, 0022h is written during the MRS cycle. Table 9–12 sum-
marizes.
