(CY). Although CLC(040) turns the Carry Flag OFF, the flag will be turned ON/
OFF by the execution of subsequent instructions which affect the Carry Flag.
Flags
Note In CS1-H, CJ1-H, CJ1M, and CS1D (for Single-CPU System) CPU Units,
these Flags are left unchanged.
In CS1 and CJ1 CPU Units, these Flags are turned OFF.
Precautions +C(402), +CL(403), +BC(406), and +BCL(407) make use of the Carry Flag in
their addition operations. Use CLC(041) just before any of these instructions
to prevent any influence from other preceding instructions.
–C(412), –CL(413), –BC(416), and –BCL(417) make use of the Carry Flag in
their subtraction operations. Use CLC(041) just before any of these instruc-
tions to prevent any influence from other preceding instructions.
ROL(027), ROLL(572), ROR(028), and RORL(573) make use of the Carry
Flag in their rotation shift operations. When using any of these instructions,
use STC(040) and CLC(041) to set and clear the Carry Flag.
Note The +(400), +L(401), +B(404), +BL(405), –(410), –L(411), –B(414), and
–BL(415) instructions do no include the Carry Flag in their addition and sub-
traction operations. In general, use these instructions when performing addi-
tion or subtraction.
