3.6.2
3.6.2.1
The time base for all NVM program or erase operations is derived from the bus block. A minimum bus frequency f
required for performing program or erase operations. The NVM module do not has any means to monitor the frequency and will
not prevent a program or erase operation at frequencies above or below the specified minimum. Attempting to program or erase
the NVM modules at a lower frequency, a full program, or erase transition is not assured.
The Flash program and erase operations are timed using a clock derived from the bus clock using the FCLKDIV and register.
The frequency of this clock must be set within the limits specified as f
The minimum program and erase times shown in
maximum times are calculated for minimum f
3.6.2.1.1
The programming time for single word programming is dependant on the bus frequency as a well as on the frequency f
and can be calculated according to the following formula.
