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.
