25.2.5
BAMRB is a 32-bit readable/writable register. BAMRB specifies bits masked in the break address
specified by BARB.
25.2.6
BDRB is a 32-bit readable/writable register. The control bits CDB1, CDB0, XYE, and XYS in
BBRB select one of the four data buses for break condition B.

R/W Break Data Bit B
Specifies bits masked in the break address of channel
B specified by BARB (BAB31 to BAB0).
0: Break address BABn of channel B is included in the
break condition
1: Break address BABn of channel B is masked and is
not included in the break condition
Note: n = 31 to 0
Stores data which specifies a break condition in
channel B.
If the I bus is selected in BBRB, the break data on IDB
is set in BDB31 to BDB0.
If the L bus is selected in BBRB, the break data on
LDB is set in BDB31 to BDB0.
If the X memory is selected in BBRB, the break data in
bits 15 to 0 in XDB is set in BDB31 to BDB16. In this
case, the values in BDB15 to BDB0 are arbitrary.
If the Y memory is selected in BBRB, the break data in
bits 15 to 0 in YDB are set in BDB15 to BDB0. In this
case, the values in BDB31 to BDB16 are arbitrary.
