10.2.2
Bus control register 2 (BCR2) is a 16-bit read/write register that selects the bus size of each area,
and whether to use the 8-bit port. It is initialized to H'3FFC by a power-on reset, but is not
initialized by a manual reset or in standby mode. Do not access external memory outside area 0
until BCR2 register initialization is complete.
Bits 15, 14, and 1—Reserved: These bits always read 0. The write value should always be 0.
Bits 2n + 1, 2n—Area n (1–6) Bus Size Specification (AnSZ1, AnSZ0): These bits specify the bus
sizes of physical space area n (n = 1 to 6).
