On page 32 - Section 8.1 /CS paragraph 2nd sentence - the data sheet said "As long as /CS is HIGH all slaves will not accept the clock signal or data and the output SDO is in high-impedance state." This will be changed to "As long as /CS is HIGH all slaves will not accept the clock signal or data and output SDO is driven in low state therefore SPI parallel connection is not supported."
