... High or LOW 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. ...
