The Windowed Watchdog Timer (WWDT) generates reset after a programmable period, if not serviced within that period. This time-out boundary is configurable, and the windowed feature allows the start time boundary to be configurable. The WWDT can generate an Interrupt, if not serviced within window (Open Window) defined by start time and time-out boundary. Also the WWDT can generate an Interrupt if serviced outside Open Window (within Closed Window). Generation of Interrupt depends on the WWDT Reaction configuration. SDL supports configuration of the watchdog timers. It also supports notification of the error via ESM interrupt. Additionally, APIs for checking the status of the watchdog timer is provided.
