The XC161’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

Note: The Flash access waitstates only affect non-sequential accesses. Due to

1) The actual access time is also influenced by the system frequency, so the frequency ranges are not fully linear.
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), Standard devices
must be operated with 2 waitstates: ((2+1) × 25 ns) ≥ 70 ns.
Grade A devices can be operated with 1 waitstate: ((1+1) × 25 ns) ≥ 50 ns.

In typical applications, eliminating one waitstate increases the average
