Description

Type

Default

PTP Rate Direction

Rate direction control for PTP clock Temporary Adjustment and Continuous

Adjustment modes.

1 = The PTP Clock Sub-nanosecond value (this register and Global PTP

Clock Sub-Nanosecond Rate Low Word Register) will be added to the PTP

time every 25MHz clock cycle.

0 = The PTP Clock Sub-nanosecond value will be subtracted from the PTP

time every 25MHz clock cycle.

R/W

PTP Temporary Adjustment Mode

1 = Enable temporary incrementing or decrementing of the PTP clock by the

PTP Clock Sub-nanosecond value (this register and the Global PTP Clock

Sub-Nanosecond Rate Low Word Register) every 25MHz clock cycle, for the

duration set in the Global PTP Clock Temp Adjustment Duration High Word

0 = Stop temporary adjustment of the PTP clock

R/W

13:0

PTP Real Time Clock Sub-Nanosecond [29:16]

This is the high word of the sub-nanosecond value of the PTP real time

clock.
