 starting low (CPOL=0) and data stabilized for sampling during the
 trailing clock edge (CPHA=1), that's SPI mode 1.
 
+Note that the clock mode is relevant as soon as the chipselect goes
+active.  So the master must set the clock to inactive before selecting
+a slave, and the slave can tell the chosen polarity by sampling the
+clock level when its select line goes active.  That's why many devices
+support for example both modes 0 and 3:  they don't care about polarity,
+and alway clock data in/out on rising clock edges.

 How do these driver programming interfaces work?
