NCONFLR is used to unlock and lock the network configuration registers which are SIR, SUBR,
GAR and SHAR. When LOCK is „ON‟, the protected registers are not able to access. In this
case a value of 0x01ACCE55 is written to NCONFLR. When LOCK is „OFF‟, the protected
registers are allowed to access. In this case any value except 0x01ACCE55 is written.
