Abstract:
1. An information transmitting apparatus comprising: a first node carrying a valid data word; a second node for carrying information to be transmitted, the information having at least three states, a first state indicating that the valid data word is to be transmitted and at least two second states, each second state representing a separate command; an interface comprising a first input coupled to the first node, a second input coupled to the second node and an output, wherein the interface is adapted to provide the valid data word when the information is in the first state, a first data word recognizable as an invalid data word when the information is in a first of the at least two second states or a second data word recognizable as an invalid data word at the output when the information is in a second of the at least two second states; an n-bit data input for carrying an actual n-bit data word to be transmitted; and a mapper coupled between the n-bit data input, the mapper adapted to selectively modify the actual n-bit data word based on a predetermined criteria, to provide the selectively modified actual n-bit data word as the valid data word to the first node, and to provide a separate output signal indicating whether or not the n-bit data word has been modified.
