11.2.2
Bus control register 2 (BCR2) is a 16-bit readable/writable register that selects the bus size of each
area. It is initialized to H'3FF0 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, 3, 2, 1, and 0—Reserved: These bits are always read as 0. The write value should
always be 0.
Bits 2n + 1, 2n—Area n (2–6) Bus Size Specification (AnSZ1, AnSZ0): Specify the bus size of
physical space area n (n
