Assumptions & limits
Assumptions & limits
- Clock rate, payload bits, framing-idle gaps. Returns Transaction time. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. SPI clock (Hz): minimum 1e-12, maximum 1000000000000.0. Payload bits: minimum 0, maximum 100000000. Framing and idle clock cycles: minimum 0, maximum 100000000. Additional chip-select gaps (seconds): minimum 0, maximum 1000000000000.0.
