What are different modes of parallel I/O? Differentiate between synchronous serial communication and asynchronous serial communication.
What are different modes of parallel I/O? Differentiate between synchronous serial communication and asynchronous serial communication. [5]
Parallel I/O is commonly implemented using programmable peripheral interface chips like the 8255A. It supports the following modes: - Provides simple input/output operations for all three ports (A, B, C). - No handshaking is required. - Any port can be configured as input or output independently....
