See instruction description for more detail. An X may be substituted for the P.**Execution time for an immediate operation = (1800+D) ns, where D = delay. This delay depends onthe distance between the I/O module and the processor module and will range from 100 to 2100 nanoseconds.For system configurations that do not include a 5026 Enclosure Model D3 or D6, the delay will range from100 to 800 nanoseconds.See key to symbols on page A-1A-10 GA34-0003
