case, the stack pointer indicates D00007 and the offset value is 3, so the data
in D00004 is overwritten.
3-17-17 STACK DATA INSERT: SINS(641)
Purpose Inserts the source data at the specified location in the stack and shifts the rest
of the data in the stack downward. The offset value indicates the location of
the desired data element (how many data elements before the current pointer
position).
This instruction is supported by CS1-H, CJ1-H, CJ1M, and CS1D CPU Units
only.
