Precaution when using PSHS instruction repeatedly
● There is a limit on the number of times the PSHS instruction can be used repeatedly. The
maximum number of times it can be used repeatedly before using the next POPS instruction
is eight.
● Please note that the program will not run correctly if this limit is exceeded.

● If the POPS instruction is used while the PSHS instruction is used repeatedly, the operation
results will be read with the result saved by the last PSHS instruction first. The numbers in
the figure correspond to the instruction results.
