1. Valid for Ambient Operating Temperature: T
2. V
3. WDI input is designed to be driven by a three-state output device. To float WDI, the “high-impedance mode” of the output
4. WDI is internally serviced within the watchdog period if WDI is left unconnected.
5. The leakage current measured on the RST pin is tested with the reset asserted (output high impedance).
