ABSTRACT:
A pseudo-synchronous fast transfer handshake protocol compatible for use on a VMS backplane bus having a master functional module and a slave functional module logically interconnected by a data transfer bus. The data transfer bus includes a data strobe signal line and a data transfer acknowledge signal line. To accomplish the handshake, the master transmits a data strobe signal of a given duration on the data strobe line. The master then awaits the reception of a data transfer acknowledge signal from the slave module on the data transfer acknowledge signal line. The slave then responds by transmitting a data transfer acknowledge signal of a given duration on the data transfer acknowledge signal line.
