MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -Registers are used for both serial to parallel and parallel to serial conversions. Registers have the ability to store and transfer data in parallel, which makes them ideal for these types of conversions.

Detailed explanation-2: -Digital parallel and serial converters adapt data transmitted in a parallel port to a serial communication format, or adapt serial port data to parallel communication format. Data converters are needed because not all devices in a system work entirely as parallel-only or serial-only components.

Detailed explanation-3: -UART: UART stands for Universal Asynchronous Receiver/Transmitter. It’s not a communication protocol like SPI and I2C, but a physical circuit in a microcontroller, or a stand-alone IC. An IC that transforms parallel data to serial in the asynchronous format and vice versa is UART.

Detailed explanation-4: -The serial-to-parallel data conversion device includes a serial data input interface that receives the serially received data and provides a received data word. A serial-to-parallel mapping circuit receives the received data word and generates memory write control and write address signals.
