One of the best places for the answer if it is not in the datasheet
could be in the Philips support group.

Great !
So, it is in the datasheet as everyone
conveyed.
It is mentioned as the endurance of flash
memory is 10000 cycles.

And there is also a Note that 'This parameter is
measured only for initial qualification and after
a design or process change that could affect
this parameter."
