A system presents a data structure over a bus which exposes, to software executing at a central processing unit (CPU), a hardware resource that is associated with a watchdog timer, attribute(s) of the watchdog timer, and (iii) commands available to the software executing at the CPU for managing the watchdog timer via one or more native CPU instructions that target the hardware resource. The system listens on the bus for a data value written to the hardware resource (i.e., by a native CPU operation issued by the software executing at the CPU), and identifies a particular command for managing the watchdog timer based on the data value written. Based on identifying the particular command, the system performs at least one of: initializing the watchdog timer, starting the watchdog timer, resetting the watchdog timer, or stopping the watchdog timer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Firmware emulated watchdog timer controlled using native CPU operations","description":"Implementing a firmware watchdog timer.
