T_A = –40°C to 125°C, V_DD = 2 V to 3.6 V
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 in 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 in Figure 4-1. This is the shortest pulse that is recognized
as an interrupt request.
