For reliable operation and to further improve immunity to harsh environment, the minimum 0.1 µF decoupling capacitor is

block should then be placed near the microprocessor clock input.

be permanently defined by the controlling signal. If the chip enable feature is not used, in active mode connect the CE pin

microprocessor, for successful start-up of the microprocessor at power-on, initial logic high level needs to be secured on

the CE pin to provide clock already during the power-on reset until the microprocessor program starts and the controlling

I/O port takes over the CE control.
