Reset Mechanisms STM32 microcontrollers support three primary reset categories: system reset, power-on reset, and backup domain reset. System reset encompasses five different reset sources, with the NRST pin reset being the most commonly used method in minimum system designs. This hardware reset triggers when the NRST pin is pulled low, resetti ...

The Inter-IC Sound (I2S) bus defines a serial link standard for streaming digital audio between integrated circuits. By routing clock and data on independent conductors, the protocol prevents timing-skew distortion, removing the need for dedicated jitter-compensation hardware in many designs. A minimal half-duplex I2S link uses three signals. T ...
