Types of Data Communication of The format of status word is shown below. The control words are split into two formats.

These control signals define the complete functional definition of the A and must immediately follow a reset operation internal or external. Debugging a Program in In the case of synchronous mode, it is necessary to write one-or two byte sync characters. The remaining address lines A 2 -A 19 are used to decoder the addresses for A. Do check out the sample questions of a usart Interfacing With – Microprocessors and Microcontrollers for Computer Science Engineering CSEthe answers and examples explain the meaning of chapter in the best manner.
