Only the values listed here are allowed. Other values will be

rejected.

Number of Sectors

1 byte

Number of continuous Flash sectors to be calculated.

Should be between 1 and 32.

E.g. if the base address is 0x10011000, and the number of

sectors is 3, it will calculate the 6 KB address starting from

0x10011000
