1) When power is first applied, the device has been held in a reset status, with respect to the write enable, in the same
way the write disable (WDS) instruction is executed. Before the write instruction is executed, the device must be
received the write enable (WEN) instruction. Once the device is done, the device remains programmable until the
write disable (WDS) instruction is executed or the supply is removed from the device.
2) It is unnecessary to add the clock after 16
th clock. If the device is recieved the clock, the device ignores the clock.
3) As both of the enable and disable instructions don’t depend on the status of the WC pin, the state of WC isn’t cared
during the instruction.
4) The instruction is recognized after the rising edge of 8 th clock for the address following 8 clocks for the opcode, but
the specified address isn’t cared during the instructions.
