10  * Checks a NID value, returns the fixed NAC, DUID and also an indication if it failed to decode the NID.
11  * \param bch_code Input. An array to the 63 bytes, each containing one bit of the NID. This includes the
12  * NAC (12 bits), DUID (4 bits) and 47 bits of BCH parity.
13  * \param new_nac Output. An address where to store the calculated NAC value after error correction. Should
14  * be large enough to accommodate for an integer.
15  * \param new_duid Output. An address where to store the calculated DUID value after error correction. Should
16  * be able to accommodate 3 chars.
17  * \param parity Input. The parity value read.
18  * \return 0 if there were errors processing the NID.
