performed for the logical addresses (and data) accessed by the executed instructions, and a
break occurs if the condition is satisfied. If the I bus is specified as a break condition, condition
comparison is performed for the physical addresses (and data) of the data access cycles that are
issued on the I bus by all bus masters including the CPU, and a break occurs if the condition is
satisfied. For details on the CPU bus cycles issued on the I bus, see 5 in section 22.3.1, Flow of
the User Break Operation.
operand size is listed in table 22.1.
This means that when address H'00001003 is set in the break address register (BARA or
BARB), for example, the bus cycle in which the break condition is satisfied is as follows
(where other conditions are met).
Longword access at H'00001000
Word access at H'00001002
Byte access at H'00001003
When the data value is included in the break conditions, either longword, word, or byte is
specified as the operand size of the break bus cycle register B (BBRB). When data values are
included in break conditions, a break is generated when the address conditions and data
conditions both match. To specify byte data for this case, set the same data in two bytes at bits
15 to 8 and bits 7 to 0 of the break data register B (BDRB) and break data mask register B
(BDMRB). When word or byte is set, bits 31 to 16 of BDRB and BDMRB are ignored.
Therefore, if including the value of the data bus when a PREF instruction is specified as a
break condition, a break will not occur.
break condition, and immediately before the next instruction is executed. However, when data
is also specified as the break condition, the break may occur on ending execution of the
instruction following the instruction that matches the break condition. If the I bus is selected,
the instruction at which the break will occur cannot be determined. When this kind of break
