(Process) (Redundant)
• 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 compare the single-precision real number data specified by (s1) with the single-precision real number data
specified by (s2), and according to the result (small, equal, or large), (d), (d)+1, or (d)+2 is turned on.
