Bit | Field | Type | Reset | Description |
---|---|---|---|---|
7 | 0 | W | 0h | Must write 0 |
6 | PLL RESET | R/W | 0h | Pulse this bit after powering up the device; see Table 75.
0 = Default 0 → 1 → 0 = The PLL RESET bit is pulsed. |
5 | LANE PDN 1 | R/W | 0h | This bit powers down unused SERDES lanes DA0, DA3, DB0, and DB3 in certain LMFS settings (applicable for LMFS = 4244, 2242, 2441, 4211, and 2221). Powering down unused lanes puts the SERDES buffers in tri-state mode and saves approximately 15-mA current on the IOVDD supply.
00 : Default 11 : DA0, DB0, DA3, and DB3 are powered down Others: Do not use |
4 | 0 | W | 0h | Must write 0 |
3 | LANE PDN 0 | R/W | 0h | This bit powers down unused SERDES lanes DA0, DA3, DB0, and DB3 in certain LMFS settings (applicable for LMFS = 4244, 2242, 2441, 4211, and 2221). Powering down unused lanes puts the SERDES buffers in tri-state mode and saves approximately 15-mA current on the IOVDD supply.
