RnPCPU
RnCPU RnENCPU
(Process)
• The RnCPU and RnENCPU with firmware version "17" or later support these instructions. (Use an engineering tool with version "1.020W" or later.)
These instructions perform a square root operation of the specified 16-bit binary data.

Processing details
• These instructions perform a square root operation of the 16-bit binary data specified by (s). and stores the result in (d).
The obtained square root is an integer because the decimal places are rounded down.
