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. In big-endian mode, it corresponds to the reading of Bits[7:0] of Register 461 (Auxiliary Timestamp - Seconds Register).
