Note:
External memory bus timing
The following sections include the External Memory Bus timings. The given values are
computed for a maximum CPU clock of 40MHz.
Obviously, when higher CPU clock frequency is used (up to 64MHz), some numbers in the
timing formulas become zero or negative which, in most cases is not acceptable or not
meaningless at all. In these cases, it is necessary to relax the speed of the bus setting
properly t
All External Memory Bus Timings and SSC Timings reported in the following tables are
granted by Design Characterization and not fully tested in production.
