ELECTRICAL CHARACTERISTICS (continued)
(V
Note 1: Devices are tested at T
Note 2: WDPO will pulse low if a falling edge is detected on WDI before this timeout period expires.
Note 3: To avoid a potential fake fault, the first WDI pulse after the rising edge of RESET or WDPO will not create a fast watchdog
Note 4: WDPO will pulse low if no falling edge is detected on WDI after this timeout period expires.
