Section 13 Bus State Controller (BSC)
13.2
13.2.1
Bus control register 1 (BCR1) is a 32-bit readable/writable register that specifies the function, bus
cycle status, etc., of each area.
BCR1 is initialized to H'00000000 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.
Notes: 1. These bits sample external pin values in a power-on reset by means of the RESET pin.
