6.2 Register Descriptions
6.2.1 Break Address Registers (BAR)
There are two break address registers—break address register H (BARH) and break address
register L (BARL)—that together form a single group. Both are 16-bit read/write registers. BARH
stores the upper bits (bits 31–16) of the address of the break condition. BARL stores the lower bits
(bits 15–0) of the address of the break condition. A reset initializes both BARH and BARL to
H'0000. They are not initialized in standby mode.
BARH: Break address register H.
