         ++__w) {                                                              \

    }

Convert a word-array to a bytes-array, effectively reverting the host-endianness to big-endian : word array to change (must be (uint16_t *) castable) @w: number of word-sized elements in the array (SENSIRION_NUM_WORDS(a)).
