12.2.1
Bus control register 1 (BCR1) is a 16-bit read/write register that sets the functions and bus cycle
state for each area. It is initialized to H'0000 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 BCR1 register
initialization is complete.
Note: * Samples the value of the external pin (MD5) designating endian at power-on reset.
Bit 15—Pins A25 to A0 Pull-Up (PULA): Specifies whether or not pins A25 to A0 are pulled up
for 4 cycles immediately after BACK is asserted.
