The timings I39 and I40 describe the testing conditions under which the IRQ lines are tested when 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 and I42 are speciÞed to allow the correct function of the IRQ lines detection circuitry, and has
no direct relation with the total system interrupt latency that the MPC823 can support.
