- * This file contains all the logic for manipulating the CAT bus
- * in a level 5 machine.
- *
- * The CAT bus is a serial configuration and test bus. Its primary
- * uses are to probe the initial configuration of the system and to
- * diagnose error conditions when a system interrupt occurs. The low
- * level interface is fairly primitive, so most of this file consists
- * of bit shift manipulations to send and receive packets on the
- * serial bus */
