1 OVERVIEW
1.2 Data Specification Method
Nibble specification range
The following table lists the range of 16-bit data for each nibble specification.
Ex.
When nibble specification is made for X0, the applicable number of points is as follows.
•K1X04 points from X0 to X3
•K2X08 points from X0 to X7
•K3X012 points from X0 to X13
•K4X016 points from X0 to X17
■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.
