7.3.15 Register Access Control

Write access to the device registers is restricted via the REG_LOCK register to prevent inadvertant changes. Any register that contains an access type of R/W is protected by REG_LOCK. The REG_ACCESS_CMD of 5Ah must be written to the REG_LOCK register to unlock the protected registers for modification. Once changes are complete, write any value other than 5Ah to the REG_LOCK register to lock the protected registers.
