Abstract
A circuit for monitoring and detecting data transfer protocol errors that occur during asynchronous transfer of data over a data bus. The circuit monitors bus request/acknowledge control lines in accordance with a predetermined handshaking protocol. In the event that an undefined or illegal logic state is detected on the data bus request or acknowledge control lines, the circuit provides an error value to the data sending entity. As a result of receiving this error value, the data sending entity can retry the data transmission over data bus.
