performed for the 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 addresses (and data) of the data access cycles on the bus
specified by the I bus select bits, and a break occurs if the condition is satisfied. For details on
the CPU bus cycles issued on the internal CPU bus, see 6 in section 7.4.1, Flow of the User
Break Operation.
operand size is listed in table 7.3.
This means that when address H'00001003 is set in the break address register (BAR), 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 in the break bus cycle register (BBR). 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 the four bytes at
bits 31 to 24, 23 to 16, 15 to 8, and 7 to 0 of the break data register (BDR) and break data mask
register (BDMR). To specify word data for this case, set the same data in the two words at bits
31 to 16 and 15 to 0.
Therefore, if including the value of the data bus when a PREF instruction is specified as a
break condition, a break will not occur.
