connect the CE pin to V
port of the clocked microprocessor, for successful startup of the microprocessor at power-on, initial logic high level needs to
be secured on the CE pin to ensure clocking occurs during the power-on reset until the microprocessor program starts and
the controlling I/O port takes over the CE control.
