Notes: 1. Set the times according to the program/erase algorithms.
2. Programming time per 32 bytes (Shows the total time the flash memory control register (FLMCR) is set. It does
3. Block erase time (Shows the period the E bit in FLMCR is set. It does not include the erase verification time.)
4. Maximum programming time
5. Number of times when the wait time after P bit setting (z) = 200 s.
6. For the maximum erase time (t
not include the programming verification time.)
(t
The maximum number of writes (N) should be set according to the actual set value of z so as not to exceed the
maximum programming time (t
(z) and the maximum number of erases (N):
t
The values of z and N should be set so as to satisfy the above formula.
Examples: When z = 5 [ms], N = 240 times
