Note: Serial Flash device can only change bits from 1 to 0 state, therefore, Sector or Chip Erase must be performed prior to programming selected addresses. 1. Bring CS low, issue WREN command, deselect CS. 2. Bring CS low, issue PROGRAM command, 3 byte address, and data byte(s) to be written. 3. Bring CS high (inactive) to start write cycle.
