Notes: 1. Follow the program/erase algorithms when making the time settings.
2. Programming time per 32 bytes. (Indicates the total time during which the P bit is set in
flash memory control register 1 (FLMCR1). Does not include the program-verify time.)
3. Time to erase one block. (Indicates the time during which the E bit is set in FLMCR1.
Does not include the erase-verify time.)
4. Maximum programming time
(max) = Wait time after P bit setting (z) × maximum number of writes (N))
