4.2.2 RESET Input Characteristics
The RESET is passed through an internal analog noise filter to prevent erroneous resets due to spikes.
The following figure shows the timing when an external reset is performed. It explains the effect of the noise
elimination.
Figure 30: External RESET timing
The analog filter generates the analog delay. The filter regards pulses up to a certain width as noise and suppresses
them.
For the minimum RESET pulse width and the minimum RESET pulse rejection, please refer to Sections 47A.5.1,
