6.2.5 Bus Release Control Register (BRCR)
BRCR is an 8-bit readable/writable register that 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.
Bits 7 to 1—Reserved: Read-only bits, always read as 1.
Bit 0—Bus Release Enable (BRLE): Enables or disables release of the bus to an external device.
