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.
