The timings I39 and I40 describe the testing conditions under which the IRQ lines are tested when being defined as
level-sensitive. The IRQ lines are synchronized internally and do not have to be asserted or negated with reference to the
CLKOUT.
The timings I41, I42, and I43 are specified to allow the correct function of the IRQ lines detection circuitry and have no direct
relation with the total system interrupt latency that the MPC860 is able to support.
