BARA = H'00037226, BAMRA = H'00000000, BBRA = H'0056, BARB = H'0003722E,
BAMRB = H'00000000, BBRB = H'0056, BDRB = H'00000000, BDMRB = H'00000000,
BRCR = H'00000008, BASRA = H'80, BASRB = H'70
Specified conditions: Channel A/channel B sequence mode
•
Channel A
Address:
H'00037226, Address mask: H'00000000, ASID = H'80
Bus cycle: CPU/instruction fetch (before instruction execution)/read/word
•
Channel B
Address:
H'0003722E, Address mask: H'00000000, ASID = H'70
Data:
H'00000000, Data mask: H'00000000
Bus cycle: CPU/instruction fetch (before instruction execution)/read/word
An instruction with ASID = H'80 and address H'00037226 is executed, and a user break occurs
before an instruction with ASID = H'70 and address H'0003722E is executed.

BARA = H'00027128, BAMRA = H'00000000, BBRA = H'005A, BARB = H'00031415,
BAMRB = H'00000000, BBRB = H'0054, BDRB = H'00000000, BDMRB = H'00000000,
BRCR = H'00300000
Specified conditions: Channel A/channel B independent mode
•
Channel A
Address:
H'00027128, Address mask: H'00000000
Bus cycle: CPU/instruction fetch (before instruction execution)/write/word
No ASID check is included
•
Channel B
Address:
H'00031415, Address mask: H'00000000
Data:
H'00000000, Data mask: H'00000000
Bus cycle: CPU/instruction fetch (before instruction execution)/read (operand size is not
included in the condition)
No ASID check is included
On channel A, no user break occurs since instruction fetch is not a write cycle. On channel B,
no user break occurs since instruction fetch is performed for an even address.
