Description

System time nanoseconds register

Fields

TSSS

Time stamp sub seconds The value in this field has the sub second representation of time, with an accuracy of 0.46 nano-second. (When TSCTRLSSR in the MAC_TIMESTAMP_CTRL register is set, each bit represents 1 ns and the maximum value will be 0x3B9A_C9FF, after which it rolls-over to zero).
PSNT

Positive or negative time This bit indicates positive or negative time value. If the bit is reset, it indicates that the time representation is positive, and if it is set, it indicates negative time value. (This bit represents the 32nd bit of the nanoseconds value when the Advance Time stamp feature is enabled).
