Accessing of Control Registers
The control registers are accessible by any master via the FPI Bus. The control registers
must be configured at initialization and then left unaltered. This is typically done by the
CPU. The only setting that can be dynamically modified is the PCP_CS.EN bit. All other
bits must only be modified when PCP_CS.EN = 0 and PCP_CS.RS = 0.
The PCP control and status registers are accessible only to the CPU when it is operating
in Supervisor mode. PCP control and status registers must be accessed with 32-bit read
and write operations only.
