Section 13 Li Bus State Controller (LBSC)
13.1.4
The bus control register 2 (BCR2) is a 16-bit read/write register that sets the bus-size width of
each area and selects whether an 8-bit port is used or not. It is initialized to H'3FF0 by a power-on
reset, but is not initialized by a manual reset or by standby mode. Do not access external memory
outside area 0 until BCR2 register initialization is complete.
Bits 15 to 8 and 5 to 0 —Not referenced
Bits 7 and 6—Area 3 Bus Size Specification (A3SZ1, A3SZ0): Specifies the bus sizes of
physical space area 3.
