REJ09B0243-0300
<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
After an instruction with address H'00037226 is executed, a user break occurs before an
instruction with address H'0003722E is executed.
(Example 1-3)

Register specifications
BARA = H'00027128, BAMRA = H'00000000, BBRA = H'005A, BDRA = H'00000000,
BDMRA = H'00000000, BARB = H'00031415, BAMRB = H'00000000, BBRB = H'0054,
BDRB = H'00000000, BDMRB = H'00000000, BRCR = H'00000000
Specified conditions: Channel A/channel B independent mode
<Channel A>
Address:
H'00027128, Address mask: H'00000000
Data:
H'00000000, Data mask: H'00000000
Bus cycle: L bus/instruction fetch (before instruction execution)/write/word
<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.
(Example 1-4)
