The two break address mask registers A (BAMRA)—break address mask register AH
(BAMRAH) and break address mask register AL (BAMRAL)—together form a single group.
Both are 16-bit read/write registers. BAMRAH determines which of the bits in the break address
set in BARAH are masked. BAMRAL determines which of the bits in the break address set in
BARAL are masked. A power-on reset initializes BAMRAH and BAMRAL to H'0000. Their
values are undefined after a manual reset.
• BAMRAH Bits 15 to 0—Break Address Mask A 31 to 16 (BAMA31 to BAMA16): These bits
specify whether bits 31–16 (BAA31 to BAA16) of the channel A break address set in BARAH
are masked.
• BAMRAL Bits 15 to 0—Break Address Mask A 15 to 0 (BAMA15 to BAMA0): These bits
specify whether bits 15–0 (BAA15 to BAA0) of the channel A break address set in BARAL
are masked.
