There are Kick and Proxy registers associated with each CTRL_MMR register partition. This section describes the Kick registers. For information about the Proxy registers see Proxy Addressing Registers.
The Kick registers provide a protection mechanism which prevents spurious writes from changing the values of its registers. The LOCKi_KICK0 and LOCKi_KICK1 registers are used for this purpose. A write is required first to the LOCKi_KICK0[31-1] KEY field and then to the LOCKi_KICK1[31-0] KEY field with exact data values to unlock the protection mechanism. Once released then all registers within Partition "i" having write permissions can be written to. The read only registers are still read only. An indication for unlocked Partition "i" is when the LOCKi_KICK0[0] UNLOCKED bit is set to 1h. When the protection mechanism is locked (indicated by LOCKi_KICK0[0] UNLOCKED = 0h) none of the registers within Partition "i" can be written to. They can only be read..
The key values for all partitions are:
See Kick Protection Registers for Partition Unlock Values.
Writing any other data value to either of these registers locks the protection mechanism and blocks any writes to the registers that reside in Partition "i".
