Value R/W Description
31 to 0 BAMB31 to
BAMB0
All 0 R/W Break Address Mask B
Specify bits masked in the break address of channel B

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.
