This application note discusses the timing requirements for the commonly used serial asynchronous communications protocol implemented in UARTs. The article shows how to determine the tolerance for the ...

This application note describes how to configure Zilog’s Z8051 Universal Serial Interface (USI) peripheral to operate as a Universal Asynchronous Receiver Transmitter (UART). C code drivers for both ...

Universal Asynchronous Receiver/Transmitters (UARTs) are considered the simplest way to send data from one system to another system. UARTs are commonly included in microcontrollers and many modern ICs ...

Edge-triggered interrupts are useful in microcontroller (MCU) applications for processing asynchronous events like switch closures, level transitions, and pulses. However, low-cost MCUs offer limited ...
