SDO: Serial Data Output
In serial microcontroller interface mode, this signal is the output data of the serial interface. Configuration or Status data at
SDO pin is clocked out of the device on the rising edge of SCLK if SCLKE pin is low, or on the falling edge of SCLK if SCLKE
pin is high.
In parallel non-multiplexed interface mode, this pin should be left open.
