1 IRQ timing specified at VDD = 1.08 V to 1.32 V, VDDEH = 3.0 V to 5.5 V, VDD33 and VDDSYN = 3.0 V to 3.6 V, TA = TL
to TH.
2 See Notes on tcyc on Figure 8 and Table 25 in Section 5.11.1 Clocking.
3 Applies when IRQ pins are configured for rising edge or falling edge events, but not both.

1 eTPU timing specified at VDD = 1.08 V to 1.32 V, VDDEH = 3.0 V to 5.5 V, VDD33 and VDDSYN = 3.0 V to 3.6 V, TA = TL to TH,
and CL = 200 pF with SRC = 0b00.
2 See Notes on tcyc on Figure 8 and Table 25 in Section 5.11.1 Clocking.
3 This specification does not include the rise and fall times. When calculating the minimum eTPU pulse width, include the rise
and fall times defined in the slew rate control fields (SRC) of the pad configuration registers (PCR).
