Data Handling Instructions 5-19
Operation
When the rung containing this instruction is true, data at the source address
passes through the mask to the destination address. See the figure below.
Mask data by resetting bits in the mask; pass data by setting bits in the mask to
one. The bits of the mask can be fixed by a constant value, or you can vary
them by assigning the mask a direct address.
TIP
Bits in the destination that correspond to zeros in the
mask are not altered.
