21.1 SYSREG Block Register Write Protection

Each SYSREG block register has dedicated write protect bits to control write access from bus masters. Write protect bits are flash configuration bits that are set based on user inputs to the MSS configurator. These bits are defined during the device design phase and can only be modified by reprogramming the device. Users have the ability to set protection levels for the entire register, independent fields within each register, or individual bits within each register.
