Section 11 Local Bus State Controller (LBSC)
Rev.1.00 Dec. 13, 2005 Page 333 of 1286
REJ09B0158-0100
The instruction to modify the value of the MMSELR should be allocated non-cacheable P2 area
and an address that will not be affected by an address map change.
Write to MMSELR before enabling the Instruction cache, Operand cache, and MMU address
translation, and then do not write to it again until after power-on reset or manual reset.
11.4.2
Bus Control Register (BCR)
BCR is a 32-bit readable/writable register that specifies the function and bus cycle status for each
area. BCR is initialized to H'0000 0000 in big endian or H'8000 0000 in little endian by a power-
on reset, but is not initialized by a manual reset mode.

Endian
Flag
The value of the external pin (MODE5) designating the
endian mode is sampled at a power-on reset by the
PRESET
pin. This bit determines the endian mode of all
spaces.
0: Indicates that the external pin (MODE5) designating
the endian mode is low at a power-on reset and big-
endian mode is specified for this LSI.
1: Indicates that the external pin (MODE5) designating
the endian mode is high at a power-on reset and
little-endian mode is specified for this LSI.

Reserved
These bits are always read as 0. The write value should
always be 0.
