By the way, this is not standardized.  The MSB-LSB order, clock phase,
transfer length, etc., change from one SPI device to another.

Things can get complicated when you have multiple devices connected to the
same SPI bus, and you need to continuously reprogram your controller when
switching from one device to another.
