space to be output from a dedicated OE pin. In this case, the OE signal for DRAM space is output
from both the RD pin and the (OE) pin, but in external read cycles for other than DRAM space,
the signal is output only from the RD pin.
6.6.6
The column address output cycle can be changed from 2 states to 3 states by setting the CAST bit
to 1 in DRAMCR. Use the setting that gives the optimum specification values (CAS pulse width,
etc.) according to the DRAM connected and the operating frequency of this LSI. Figure 6.22
shows an example of the timing when a 3-state column address output cycle is selected.
