DESCRIPTION

Chip Enable: CE# goes low activates the device's internal circuitries for

device operation. CE# goes high deselects the device and switches into

standby mode to reduce the power consumption. When the device is not

selected, data will not be accepted via the serial input pin (Sl), and the

serial output pin (SO) will remain in a high impedance state.
