6.2.5 Bus Release Control Register (BRCR)
BRCR is an 8-bit readable/writable register that enables address output on bus lines A
and enables or disables release of the bus to an external device.
BRCR is initialized to H'FE by a reset and in hardware standby mode. It is not initialized in
software standby mode.
