12.9 CONTROL PIN CHARACTERISTICS
12.9.1 Asynchronous RESET Pin
Subject to general operating conditions for V
Notes:
1. Data based on characterization results, not tested in production.
2. Hysteresis voltage between Schmitt trigger switching levels.
3. The I
(I/O ports and control pins) must not exceed I
4. To guarantee the reset of the device, a minimum pulse has to be applied to the RESET pin. All short pulses applied on
the RESET pin with a duration below t
5. The reset network (the resistor and two capacitors) protects the device against parasitic resets, especially in noisy en-
vironments.
6. Data guaranteed by design, not tested in production.
