Figure 26. Asynchronous External Master – Control Signals Negation Time
Notes:
1. 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.
2. The timings I41, I42 and I43 are specified to allow the correct function of the IRQ lines detection circuitry, and has no direct
relation with the total system interrupt latency that the TSPC860 is able to support.
