Interrupt signals are synchronized internally and are potentially recognized one cycle later if setup and hold times are violated. Thus, they can
be connected to asynchronous inputs.
P = 1/CPU clock frequency in ns. For example, when running parts at 167 MHz, use P = 6 ns.
*This parameter is not tested.

§ P = 1/CPU clock frequency in ns. For example, when running parts at 167 MHz, use P = 6 ns.
When the PLL is used (CLKMODE x4), 0.5P = 1/(2
× CPU clock frequency).
For CLKMODE x1: 0.5P = PH, where PH is the high period of CLKIN.
