External memory bus timing
In the next sections the external memory bus timings are described. The given values are
computed for a maximum CPU clock of 40 MHz.
It is evident that when higher CPU clock frequency is used (up to 64 MHz), some numbers in
the timing formulas become zero or negative, which in most cases is not acceptable or
meaningful. In these cases, the speed of the bus settings t
adjusted.
All external memory bus timings and SSC timings presented in the following tables are given
by design characterization and not fully tested in production.
