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.
