WREN / WRDS ( Write Enable and Write Disable )

When Vcc is applied to the part, it powers up in the programming disable (WRDS) state. Programming must

be preceded by a programming enable (WREN) instruction. Programming remains enabled until a

programming disable (WRDS) instruction is executed or Vcc is removed from the part. The programming

disable instruction is provided to protect against accidental data disturb. Execution of a read instruction is not

affected by both WREN and WRDS instructions.
