8.5.1 Example Register Writes

This section provides three different example register writes. Table 16 describes a global power-down register write, Table 17 describes the register writes when the default lane setting (eight active lanes per device) is changed to four active lanes (LMFS = 4211), and Table 18 describes the register writes for 2X decimation with four active lanes (LMFS = 4222).
