Description

Sets the order of the bits shifted out of and into the SPI bus, either LSBFIRST (least-significant bit first) or MSBFIRST (most-significant bit first).

Extended method for Arduino Due
If you specify one of the Arduino Due's Slave Select (SS) pin in the call to setBitOrder(), the bit order setting is applied only to the device connected to the specified SS pin. More info on extended methods: Due Extended SPI usage
