Locked Locked The servo is adjusting (synchronizing) to the
master clock.
Not Applicable NotApplicable The servo state is currently not applicable.
PTP Master Clock Identity ptpMasterClockId Port identity of the current best master. The clock
ID is an Extended Unique Identifier (EUI)-64 64-
bit ID, converted from the 48-bit MAC address, by
inserting 0xfffe at the middle of the MAC address.

PTP Master Offset ptpMasterOffsetNs Dynamically returns the 64-bit value of the PTP
offset with the master. This value is the input for
clock corrections for the slave device clock servo
algorithms.

PTP Servo Step Threshold
(in us)
ptpServoStepThreshold Specifies the servo step threshold (in us). When
the clock offset with the master exceeds the
threshold, the servo unlocks and offset adjustment
is started.

Timestamp Modulo Event timestampModulo Specifies the additional interval between the
current timestamp tick and the event generated.
This interval has an 80ns accuracy. Note that the
value zero disables the event generator.

Timestamp Modulo Event
Frequency
timestampModuloFrequency Returns the frequency of the timestamp Modulo
Event (in Hz).

Timestamp Modulo Start
Time
timestampModuloStartTime Specifies the timestamp value that must be
exceeded by the incrementing timestamp counter
before the modulo event starts. This Feature is
also used for a “Future” Frame Acquisition.
