Section 11 Local Bus State Controller (LBSC)
Example:
Modify executing instruction of MMSELR should allocate non-cacheable P2 area and the address
that should not be affected by address map change.
Write to MMSELR before enable Instruction cache, Operand cache, and MMU address translation
and after this never write again until execute power-on reset or manual reset.
11.4.2
The bus control register (BCR) is a 32-bit readable/writable register that specifies the function and
bus cycle status for each area. It is initialized to H'0000 0000 in big-endian mode or H'8000 0000
in little-endian mode by a power-on reset or a mammal reset.
