1.
Data based on characterization results, not tested in production.
2.
Hysteresis voltage between Schmitt trigger switching levels.
3.
The IIO current sunk must always respect the absolute maximum rating specified in Section 12.2.2: Current characteristics
on page 314 and the sum of IIO (I/O ports and control pins) must not exceed IVSS.
4.
To guarantee the reset of the device, a minimum pulse has to be applied to the RESET pin. All short pulses applied on
RESET pin with a duration below th(RSTL)in can be ignored.
5.
The reset network protects the device against parasitic resets.
