Section 7 User Break Controller (UBC)
<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.
(Example 1-5)

BARA = H'00000500, BAMRA = H'00000000, BBRA = H'0057, BDRA = H'00000000,

Specified conditions: Channel A/channel B independent mode
<Channel A>
Address: H'00000500, 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)
<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
On channel A, a user break occurs after the instruction of address H'00000500 is executed four
times and before the fifth time.
On channel B, a user break occurs before an instruction of address H'00001000 is executed.
