4.4.2
The XC164CM’s Flash module delivers data within a fixed access time (see
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
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%.

Erase time per sector
1) The actual access time is influenced by the system frequency, see
2) Programming and erase time depends on the system frequency. Typical values are valid for 40 MHz.
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.
