Instruction Execution Times
This following table lists the execution times for all instructions that are available for the K-types. The maxi-
mum and minimum execution times and the conditions which cause them are given where relevant.
Execution times for most instructions depend on whether they are executed with an ON or an OFF execution
condition. The OFF execution time for an instruction can also vary depending on the circumstances, i.e.,
whether it is in an interlocked program section and the execution condition for IL is OFF, whether it is between
JMP(04) 00 and JME(05) 00 and the execution condition for JMP(04) 00 is OFF, or whether it is reset by an
OFF execution condition. “R,” “IL,” and “JMP” are used to indicate these three times.
Execution times are expressed in microseconds except where noted.
