PARAMETER
TEST CONDITIONS
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
oscillator is used.
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
chip.
Interrupt pulse duration
See item 2, Figure 4-1.This is the shortest pulse that is recognized as
an interrupt request.
