Detailed explanation-1: -In general, a standard low-cost, ceramic resonator with ±0.5% accuracy and a further ±0.5% drift over temperature and life can be used for the clock source at both ends of the link.
Detailed explanation-2: -A USART (universal synchronous/asynchronous receiver/transmitter) is hardware that enables a device to communicate using serial protocols. It can function in a slower asynchronous mode, like a universal asynchronous receiver/transmitter (UART), or in a faster synchronous mode with a clock signal.
Detailed explanation-3: -One of the most common timing-sensitive tasks is UART communication. The interface lacks an external clock, and the Tx and Rx devices can reliably share data only when their internal baud rates are equal.
