Note:

200 ns minimum in Software Standby mode.

Note:

If the clock source is switched, add 4 clock cycles of the 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.

Note:

tPcyc: PCLKB cycle, tPDcyc: PCLKD cycle.

Note 1. This skew applies when the same driver I/O is used. If the I/O of the middle and high drivers is mixed, operation is not guaranteed.

Note 2. Constraints on input cycle:

When not switching the source clock: tPcyc × 2 < tACYC should be satisfied.
