Data Movement Instructions Section 5-17
5-17-2 MOVE NOT – MVN(22)
Limitations DM 6144 to DM 6655 cannot be used for D.
Description When the execution condition is OFF, MVN(22) is not executed. When the
execution condition is ON, MVN(22) transfers the inverted content of S (spec-
ified word or four-digit hexadecimal constant) to D, i.e., for each ON bit in S,
the corresponding bit in D is turned OFF, and for each OFF bit in S, the corre-
sponding bit in D is turned ON.
Precautions TC numbers cannot be designated as D to change the PV of the timer or
counter. However, these can be easily changed using BSET(71).
Flags ER: Indirectly addressed DM word is non-existent. (Content of *DM word
is not BCD, or the DM area boundary has been exceeded.)
EQ: ON when all zeros are transferred to D.
Example The following example shows @MVN(22) being used to copy the complement
of #F8C5 to DM 0010 when IR 00001 goes from OFF to ON.
S: Source word
IR, SR, AR, DM, HR, TC, LR, #
D: Destination word
IR, SR, AR, DM, HR, LR
