ABSTRACT:
A data transmission apparatus is disclosed which is of the type in which data generated therein by two data generating blocks are transmitted through a bus common to these blocks. One data generating block generates a data validating signal which indicates that the data to be transmitted thereby is valid and delivers the data to a bus, while the other data generating block is inhibited from outputting its data when the data validating signal exists.
