7 APPLICATION INSTRUCTION
7.10 Data control instruction
Scaling 16-bit binary data (point coordinates)
SCL(P)(_U)
These instructions process the scaling conversion data (in 16-bit data units) specified by (s2) by scaling it based on the input
value specified by (s1), and store the operation result in the device specified by (d).
■Descriptions, ranges, and data types
*1 The number of coordinate points of (s2) is 16-bit unsigned binary data.
■Applicable devices
• These instructions process the scaling conversion data (in 16-bit data units) specified by (s2) by scaling it based on the
input value specified by (s1), and store the operation result in the device number specified by (d). The scaling conversion is
performed based on the scaling conversion data stored in the device specified by (s2) and later.
