Break ASID register A (BASRA) is an 8-bit readable/writable register that specifies the ASID
used in the channel A break conditions. BASRA is not initialized by a power-on reset or manual
reset.
Bits 7 to 0—Break ASID A7 to A0 (BASA7–BASA0): These bits hold the ASID (bits 7–0) used
in the channel A break conditions.

Break address mask register A (BAMRA) is an 8-bit readable/writable register that specifies
which bits are to be masked in the break ASID set in BASRA and the break address set in BARA.
BAMRA is not initialized by a power-on reset or manual reset.
Bits 7 to 4—Reserved: These bits are always read as 0, and should only be written with 0.
Bit 2—Break ASID Mask A (BASMA): Specifies whether all bits of the channel A break ASID7
to ASID0 (BASA7–BASA0) are to be masked.
Bit 2: BASMA

Description
All BASRA bits are included in break conditions
