The BCFG register cannot be written when blink is enabled. The blink frequency can be modified,
provided the selected frame counter has been disabled first.

43.6.2.4. Autonomous Segment Animation
Up to sixteen segments can be animated by an internal circular shift register. Up to sixteen states are
then defined, e.g. to make a running wheel. The size of the animation can be configured by writing the
number of segments to use to the Size bits in the Circular Shift Register Configuration register
(CSRCFG.SIZE).
The circular shift register bits are associated to segments connected to SEG2, SEG3 and COM[0..7]
lines, refer to the table below.
