CONDITION CODE COMPUTATION
A - 18
INSTRUCTION SET DETAILS
MOTOROLA
C (Carry Bit)
Set if a carry is generated out of the MS bit of the A or B result of
an addition or if a borrow is generated out of the MS bit of the A
or B result of a subtraction. The carry or borrow is generated out
of bit 55 of the A or B result. Cleared otherwise.
Table A-5 shows how each condition code bit is affected by each instruction. Exceptions
to the standard definitions given above are indicated by a number or a “?”. Consult the
corresponding note for the special definition that applies in each particular case.
Although many of the instructions allow optional parallel moves, Table A-5 applies when
there are no parallel moves associated with an instruction. With this restriction, the
states of the condition code bits are determined only by the execution of the instruction
itself. However, the S and L bits may be determined differently than shown in the table
when a parallel move is associated with the instruction. When using an optional parallel
move, refer to the individual instruction’s detailed description in Section A.7 to see how
the S and L bits are determined.
