Read returns zero.
Powerdown.
0 = Normal operation.
1 = Powers down the Si2401.
Powerdown Line-Side Chip (typically only used for board level debug.)
0 = Normal operation. Program the clock generator before clearing this bit.
1 = Places the line-side device in lower power mode.
Line Voltage Force Disable.
0 = Normal operation.
1 = The circuitry that forces the LVS register to all 0s at 3 V or less is disabled. This reg-
ister may display unpredictable values at voltages between 0 to 2 V. All 0s are displayed
if the line voltage is 0 V.
Do not modify.
Hybrid Transmit Path Connect.
0 = Disable.
1 = Enable.
Do not modify.
