2 Instruction Descriptions
In the following programming, upward differentiation of x[i] is determined by the R_TRIG instruction.
An instance of the R_TRIG instruction is provided for each element of x[i], so it is possible to detect
which element of x[i] changed its value. As a result, Count2[0] to Count2[10] are all incremented.
