System Control Module (SCM)
At reset, these on-chip modules are configured to have only supervisor read/write access capabilities. Bit
encodings for the ACCESS_CTRL field in the GPACR are shown in
memory space protected by the GPACRs and the modules mapped to these spaces.

Bits
This bit, once set, prevents subsequent writes to the GPACR. Any attempted write to the
GPACR generates an error termination and the contents of the register are not affected.
Only a system reset clears this flag.
Reserved, should be cleared.
