On-chip Flash Operation
The XC164GM’s Flash module delivers data within a fixed access time (see Table 17).
Accesses to the Flash module are controlled by the PMI and take 1+WS clock cycles,
where WS is the number of Flash access waitstates selected via bitfield WSFLASH in
register IMBCTRL. The resulting duration of the access phase must cover the access
time
t
ACC of the Flash array. The required Flash waitstates depend on the actual system
frequency.
The Flash access waitstates only affect non-sequential accesses. Due to prefetching
mechanisms, the performance for sequential accesses (depending on the software
structure) is only partially influenced by waitstates.
In typical applications, eliminating one waitstate increases the average performance by
5% … 15%.
Example: For an operating frequency of 40 MHz (clock cycle = 25 ns), the Flash
accesses must be executed with 1 waitstate: ((1+1)
× 25 ns) ≥ 50 ns.
Table 18 indicates the interrelation of waitstates and system frequency.
Note: The maximum achievable system frequency is limited by the properties of the
respective derivative, i.e. 40 MHz (or 20 MHz for XC164GM-xF20F devices).
