/**
* Drives up to 8 digits using two 8-bit shift registers.
*
* Least significant bit ends up at output pin 0 of the shift register,
* which correlates to Segment A (as defined in SegmentDisplayChars.h).
* The last digit is also assumed to be at output pin 0 of the chained
* shift register.
*
* The order in which the shift registers are chained is determined by
* (un)defining SDPushSegmentsFirst.
