Bits 6:4 are encoded to set the maximum transferred line size. If the field is not set to unlimited if the client sending data into the VPDMA exceeds the maximum allowed pixels the data will continue to be received from the client but will not be sent to external memory until an end of line is received from the client sending data. The outbound descriptor if created will still have the transmitted size of the last line of the frame which will match the max width. If the frame does not exceed the max width then the actual transmitted size will be placed in the descriptor. Tiled clients such as the noise filter should always set this to 0. If Max Width is 0 and the line size is larger then 4096 pixels then the address counters will overflow and the data at the start of the line will be overwritten.
