1) When CS is “HIGH” during power up, BR9080AF-W / ARFV-W / ARFVM-W, BR9016AF-W / ARFV-W / ARFVM-W
comes up in the write disabled (WDS) state. In order to be programmable, it must receive a write enable (WEN)
instruction.
The device remains programmable until a disable (WDS) instruction is entered, or until it is powered down.
2) It is unnecessary to add the clock after 16th clock.
