Description
Transmit Amplitude Selection
The TXO[1:0] field sets the transmit output amplitude to account for
transmit transformer insertion loss.
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.
