System clock is when 32 MHz crystal oscillator is used.
System clock is 16 MHz when high speed RC oscillator
is used.
See item 1, Figure 1. This is the shortest pulse that is
guaranteed to be recognized as a reset pin request.
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.
