Manufacturer:AT Description:Chip Select Input. CS HIGH, deselects the device and the SO output pin is at a high impedance state. Unless a nonvolatile write cycle is underway, the device will be in the standby power mode. CS LOW enables the device, plac- ing it in the active power mode. Prior to the start of any operation after power up, a HIGH to LOW transition on CS is required. Watchdog Input. A HIGH to LOW transition on the WDI pin restarts the watch- dog timer. The absence of a HIGH to LOW transition within the watchdog time out period results in RESET/RESET going active. |
