An Abort Channel descriptor is used to clear a channel. This clears the channel from issuing any more requests. Any outstanding requests for that channel will complete as originally scheduled. All data inside the client will be flushed. For Tiled Clients such as the noise filter it is required to issue two consecutive abort channel descriptors to ensure the channel is aborted for both the current tile and next tile. Word 0, Word 1 and Word 2 are reserved.
