Description
Break Address Mask B
Specify bits masked in the break address of channel B
specified by BARB (BAB31 to BAB0).

Description
Break Data Bit B
Store 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.
