Chapter 6 Applied Instructions Symbol S 1 ： Data source S 2 ： Parameter D ： Destination device 6_ Explanation 1. This instruction finds a scaled linear value for the value in S 1 using two points in S 2 to define the scaling factor, and stores the result in D . 2. Only the 32-bit instructions can use the 32-bit counter, but not the device E. 3. The following table list the constant usage for the operand S 1 The flag SM685 (whether to use floating point operation or not) can only be used for 32-bit instructions.
