Example: Pseudo-static RAM may have separate OE and RFSH pins, or these may be combined
into a single OE/RFSH pin. Figure 7-17 shows an example of a circuit for generating an
OE/RFSH signal. Check the device characteristics carefully, and design a circuit that fits them.
Figure 7-18 shows a setup procedure to be followed by a program.
