Notes: 1. Settings of each time must comply with algorithm of writing/erasing.
2. Writing time for 128 bytes: indicates the total period in which bit P of flash memory control register 1 (FLMCR1)
is set. Writing verification time is not included.
3. Erasing time for one block: indicates the period in which bit E of FLMCR1 is set. Erasing verification time is not
included.
4. Maximum writing time: tP(max) = Σ wait time (z) after setting of bit P
