PTP Real Time Clock 8ns Phase

This register indicates one of the 8n sub-cycle phases of the 40ns period

PTP real time clock.

000 = 0ns (real time clock at the first 8ns phase in the 40ns period)

001 = 8ns (real time clock at the second 8ns phase in the 40ns period)

010 = 16ns (real time clock at the third 8ns phase in the 40ns period)

011 = 24ns (real time clock at the fourth 8ns phase in the 40ns period)

100 = 32ns (real time clock at the fifth 8ns phase in the 40ns period)

101 - 111 = not valid
