Section 18 User Break Controller (UBC)
• Register specifications
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: L bus/instruction fetch (before instruction execution)/write/word
The ASID check is not included.
 Channel B
Address: H'00031415, Address mask: H'00000000
Data: H'00000000, Data mask: H'00000000
Bus cycle: L bus/instruction fetch (before instruction execution)/read (operand size is not
included in the condition)
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.

BARA = H'00037226, BAMRA = H'00000000, BBRA = H'005A, BARB = H'0003722E,
BAMRB = H'00000000, BBRB = H'0056, BDRB = H'00000000, BDMRB = H'00000000,
BRCR = H'00000008
Specified conditions: Channel A/channel B sequential mode
 Channel A
Address: H'00037226, Address mask: H'00000000
Bus cycle: L bus/instruction fetch (before instruction execution)/write/word
 Channel B
Address: H'0003722E, Address mask: H'00000000
Data: H'00000000, Data mask: H'00000000
Bus cycle: L bus/instruction fetch (before instruction execution)/read/word
Since instruction fetch is not a write cycle on channel A, a sequential condition does not
match. Therefore, no user break occurs.
