EWEN / EWDS

When Vcc is applied to the part, the part automatically powers up in the ERASE/WRITE Disable state. In the

ERASE/WRITE disable state, execution of WRITE instruction is disable. Before WRITE instruction is

executed, EWEN instruction must be executed. The ERASE/WRITE enable state continues until EWDS

instruction is executed or Vcc is removed from the part.

Execution of a read instruction is independent of both EWEN and EWDS instructions.
