Reserved.

[7:4]RevAnd

This field indicates minor errata fixes specific to this design, for example metal fixes after implementation. In most cases this field is zero. It is recommended that component designers ensure this field can be changed by a metal fix if required, for example by driving it from registers that reset to zero.

0x0 = Indicates that there have been no metal fixes to this component.

[3:0]Customer_Modified

Where the component is reusable IP, this value indicates if the customer has modified the behavior of the component. In most cases this field is zero.
