lines are tested when being defined as level-sensitive. The IRQ lines are
synchronized internally and need not 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 MPC852T is able to support.
The timings I39 and I40 describe the testing conditions under which the IRQ
