Hi, I am working on a small design using Intel 386EXTC processor. The design has a 512KB Flash and a 512KB SRAM. The processor user manual says "The chip-selects generated by this unit can simplify external "glue logic" by providing signals that can be connected directly to the chip-enable inputs of external memory and I/O devices."
My question is if I am using 8bit memories, is it possible that I can take UCS and connect it directly to Flash that has startup information and CS0 to SRAM? Is there a necessity of glue logic? If yeah, how can I do that using A15:A25 address lines and get the CE for SRAM and FLASH?
Also, do I need a 50MHz external oscillator that will be the input at pin clk2 for 25MHz operation of processor?
