Diesel Version 5:CV 31

Indexed CV High Byte

The Indexed Address is the address of the indexed CV page when the decoder is set up for indexed CV operation. CV#31 contains the most significant bits of the two byte address and may have any value between 16 and 255 inclusive. Values of 0 thru 15 are reserved by the NMRA for future use. CV32 contains the least significant bits of the index address and may contain any value.

This gives a total 61,440 indexed pages each with 256 CV's in each page for a total of 15,728,640 indexed CV's!
(High byte 240 * Low Byte 256 * bytes per page 256) = total number of available CV's
