Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Loopback Mode Enable
When set, forces a loopback within the digital block to provide information
on input and unique numbering.
The 10-bit loopback data is defined as shown in the read for bits 9:0
above.
