• A 8-byte write is possible using this command.
• Th page write command arbitrarily sets the upper four bits (WA6 to WA3) of the word address. The lower three bits
(WA2 and WA0) can write up to eight bytes of data with the address being incremented internally.

• A 16-byte write is possible using this command.
• Th page write command arbitrarily sets the upper four bits (WA7 to WA4) of the word address. The lower four bits
(WA3 and WA0) can write up to sixteen bytes of data with the address being incremented internally.
