Section 9 User Break Controller
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,

BRCR = H'00000008, BASRA = H'80, BASRB = H'70
Specified conditions: Channel A/channel B sequential mode
<Channel A>
Address: H'00037226, Address mask: H'00000000, ASID = H'80
Bus cycle: L bus/instruction fetch (before instruction execution)/write/word
<Channel B>
Address: H'0003722E, Address mask: H'00000000, ASID = H'70
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.

BRCR = H'00300001, BETR = H'0005
Specified conditions: Channel A/channel B independent mode
<Channel A>
Address: H'00000500, Address mask: H'00000000
Bus cycle: L bus/instruction fetch (before instruction execution)/read/longword
The ASID check is not included.
<Channel B>
Address: H'00001000, Address mask: H'00000000
Data:
H'00000000, Data mask: H'00000000
Bus cycle: L bus/instruction fetch (before instruction execution)/read/longword
The number of execution-times break enable (5 times)
The ASID check is not included.
On channel A, a user break occurs before an instruction of address H'00000500 is executed.
On channel B, a user break occurs after the instruction of address H'00001000 are executed
four times and before the fifth time.
