3. When the data value is included in the break conditions on B channel:
4. When the DMAC data access is included in the break condition:
break condition is executed and then the break is generated prior to the execution of the next
instruction. As with pre-execution breaks, this cannot be used with overrun fetch instructions.
When this kind of break is set for a delay branch instruction, the break is generated at the
instruction that then first accepts the break.
There is thus no need to set break data for the break of the instruction fetch cycle.
operand size are listed in table 8.2:
This means that when address H'00001003 is set without specifying the size condition, 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 registers (BBRA and 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.
When the address is included in the break condition on DMAC data access, the operand size of
the break bus cycle registers (BBRA and BBRB) should be byte, word or no operand size
specification. When the data value is included, select either byte or word.
