13.2.2
Bus control register 2 (BCR2) is a 16-bit readable/writable register that specifies the bus width for
each area, and whether a 16-bit port is used.
BCR2 is initialized to H'3FFC by a power-on reset, but is not initialized by a manual reset or in
standby mode. External memory space other than area 0 should not be accessed until register
initialization is completed.
Note:
Bits 15 and 14—Area 0 Bus Width (A0SZ1, A0SZ0): These bits sample the external pins, MD4
and MD3 that specify the bus size in a power-on reset by the RESET pin. They are read-only bits.
