The status word is not affected.
Program display instruction:
is treated by the CPU like a null operation instruction.
Null operation instruction
Detection of an edge change. The current
signal state of the RLO is compared with the
signal state of the instruction or edge bit
memory.
FP detects a change in the RLO from "0" to "1".
FN detects a change in the RLO from "1" to
"0".
Detecting the positive edge in the RLO. The bit addressed
Detecting the negative edge in the RLO. The bit addressed
