6.2.3
The break bus cycle register (BBR) is a 16-bit read/write register that selects the following four
break conditions:
•
•
•
•
A reset initializes BBR to H'0000. It is not initialized in the standby mode.
BAMRL bits 15–0 (break address mask 15–0 (BAM15–BAM0)): BAM15–BAM0 specify
whether bits BA15–BA0 of the break address set in BARH are masked or not.
