150 / 172 page  ST72260Gx, ST72262Gx, ST72264Gx 150/172 13.9 CONTROL PIN CHARACTERISTICS 13.9.1 Asynchronous RESET Pin TA = -40 to +85°C unless otherwise specified Figure 90. Typical IPU on RESET pin Notes: 1. Data based on characterization results, not tested in production. 2. The IIO current sunk must always respect the absolute maximum rating specified in Section 13.2.2 and the sum of IIO (I/O ports and control pins) must not exceed IVSS. 3. 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.
