8.4.2
The bus control register 2 (BCR2) is a 16-bit read/write register that selects the bus-size width and
8-bit port of each area. 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.
