/*! \NOTE the uint_fast8_t used in this header file is defined in stdint.h

          a. if the target processor is 8 bits, define it as uint8_t
          b. if the target processor is 16 bits, define it as uint16_t
          c. if the target processor is 32 bits, define it as uint32_t
          d. if the target processor is 64 bits, define it as either uint32_t or
