The I39 and I40 timings 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 I41, I42, and I43 timings are specified to allow correct functioning of the IRQ lines detection circuitry and have no direct
relation with the total system interrupt latency that the MPC875/MPC870 is able to support.
