  29  * @brief Static initialisation of non-zero variables
  30  *
  31  * This file contains static initialisations for fields that require a non-zero
  32  * initial value after reset. Zero fields are taken care of by GCC and doing
  33  * this here means less init time and init code, both good things. Variables
  34  * initialised here are placed together by the compiler in flash and copied up
  35  * to RAM as a linear block before the main method runs. This is significantly
  36  * more efficient than doing them one-by-one in an init routine.
