gmacgrp_auxiliary_timestamp_nanoseconds

         This register, along with Register 461 (Auxiliary Timestamp  Seconds Register), gives the 64-bit timestamp stored as auxiliary snapshot. The two registers together form the read port of a 64-bit wide FIFO with a depth of 16. Multiple snapshots can be stored in this FIFO. The ATSNS bits in the Timestamp Status register indicate the fill-level of this FIFO. The top of the FIFO is removed only when the last byte of Register 461 (Auxiliary Timestamp - Seconds Register) is read. In the little-endian mode, this means when Bits[31:24] are read.

Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.
