Fixed‑point arithmetic is widely used in low‑power MCUs to avoid the area and energy overhead of floating‑point units (FPUs) while retaining deterministic execution times. The TIMER0 peripheral in the SONE line implements a 32‑bit fixed‑point counter with a 16‑bit fractional part, enabling sub‑microsecond resolution without floating‑point hardware [1].
If you have tried everything above and the error persists, you need to eliminate third-party software conflicts. sone033 fixed
Formal methods, especially model checking with timed automata (UPPAAL) and SAT‑based equivalence checking, have proved effective for uncovering hidden timing bugs [4]. Our approach adapts these techniques to the SONE micro‑architecture, focusing on the interaction between the DMA arbiter and TIMER0. Fixed‑point arithmetic is widely used in low‑power MCUs
