Note: 1. WA=Word Address in targeted bank, BKA= Bank Address, PD=Program Data, BA=Block Address.
2. WA1 is the Start Address. NOT WA1 is any address that is not in the same block as WA1.
3. Address can remain Starting Address WA1 or be incremented.
4. Word Addresses 1 and 2 must be consecutive Addresses differing only for A0.
5. Word Addresses 1,2,3 and 4 must be consecutive Addresses differing only for A0 and A1.
6. A Bus Read must be done between each Write cycle where the data is programmed or verified to read the Status Register and
check that the memory is ready to accept the next data. n = number of Words, i = number of Pages to be programmed.
7. Address is only checked for the first Word of each Page as the order to program the Words in each page is fixed so subsequent
Words in each Page can be written to any address.
8. Any address within the bank can be used.
9. Any address within the block can be used.
