DESCRIPTION
PowerOnToPowerGoodTime
This field value is represented as the number of 2 ms intervals, which ensuring
that the power switching is effective within 2 ms. Only bits [25:24] is implemented
as R/W. The remaining bits are read only as ‘0’. It is not expected that these bits
be written to anything other than 1h, but limited adjustment is provided. This field
should be written to support system implementation. This field should always be
written to a non-zero value.

NoOverCurrentProtection
Global over-current reporting implemented in HYDRA-2. This bit should be written
to support the external system port over-current implementation.
0 = Over-current status is reported
1 = Over-current status is not reported
OverCurrentProtectionMode
Global over-current reporting implemented in HYDRA-2. This bit should be written
0 and is only valid when NoOverCurrentProtection is cleared.
0 = Global Over-Current

NoPowerSwitching
Global power switching implemented in HYDRA-2. This bit should be written to
support the external system port power switching implementation.
0 = Ports are power switched.
1 = Ports are always powered on.
PowerSwitchingMode
Global power switching mode implemented in HYDRA-2. This bit is only valid
when NoPowerSwitching is cleared. This bit should be written '0'.
