See item 1, Figure 1. This is the shortest pulse that is
guaranteed to be recognized as a complete reset pin
request. Note that shorter pulses may be recognized but
will not lead to complete reset of all modules within the
chip.

See item 2, Figure 1.This is the shortest pulse that is
guaranteed to be recognized as an interrupt request. In
PM2/3 the internal synchronizers are bypassed so this
requirement does not apply in PM2/3.
