- A what-if question;
-
- I'm designing a memory controller to interface to the 80C188EA. According
- to the timing diagrams, there a three cycle status bits S(2:0) which are
- valid before the T1 state. The read or write command is valid during the
- T2 state. My question is this; if I know what kind of cycle I'll be
- performing even before the command is given, can I let my memory state
- machine just look at these status bits when I latch the address, instead
- of waiting around for the command.
