■
Specifying a bit device with nibble specification in the source (s)
When a bit device with nibble specification is specified in the source of an instruction, 0 is stored in the bits, which follow the
bit for which nibble specification is made in the source, in the word device of the destination.
■
Specifying a bit device with nibble specification in the destination (d)
When a nibble specification is made in the destination of an instruction, the number of points by the nibble specification is
applicable in the destination.
The bit devices after the number of points specified by nibble remain unchanged.
Handling 32-bit data with word devices/labels
■
Word device
Two points of word device can handle 32-bit data.
Note, however, that one point of the following devices can handle 32-bit data.
• Long counter (LC)
• Long index register (LZ)
■
Double word type label
One point of double word device can handle 32-bit data.
Ladder example
Processing
• 32-bit data instruction
Ladder example
Processing
• When the source data is a word device
(1): The data remain the same.
