Controlling Column Address Output Cycle
The number of column address output cycles can be changed from two to three clock cycles by
setting the CAST bit in DRAMCR. Set the bit according to the DRAM to be used and the
frequency of this LSI so that the
CAS pulse width can be optimal.
Figure 6.39 shows a timing example when the number of column address output cycles is set to
three clock cycles.
