Electrical Parameters
Access to the XC228xM Flash modules is controlled by the IMB. Built-in prefetch
mechanisms optimize the performance for sequential access.
Flash access waitstates only affect non-sequential access. Due to prefetch
mechanisms, the performance for sequential access (depending on the software
structure) is only partially influenced by waitstates.
