Note: If the clock source is being switched it is needed to add 4 clock cycle of switched source. Note 1. tPcyc indicates the PCLKB cycle. Note 2. tNMICK indicates the cycle of the NMI digital filter sampling clock. Note 3. tIRQCK indicates the cycle of the IRQi digital filter sampling clock (i = 0 to 7). tNMIW NMI Figure 2.12 NMI interrupt input timing RA2L1 Datasheet 2.
