System clock, f_SYSCLK
t_SYSCLK = 1/ f_SYSCLK
The undivided system clock is 32 MHz when crystal oscillator is used.
The undivided system clock is 16 MHz when calibrated 16-MHz RC

RESET_N low duration
See item 1, Figure 4-1. This is the shortest pulse that is recognized as
a complete reset pin request. Note that shorter pulses may be
recognized but do not lead to complete reset of all modules within the
1
chip.
Interrupt pulse duration
