  32  * This file defines the pin specific names for each interrupt and all of it's
  33  * pin specific variables then imports the actual code from inc/injectorISR.c
  34  * for each pin such that each one is unique and references a separate set of
  35  * values specific to it while only maintaining a single copy of the code.
