gmacgrp_system_time_nanoseconds

         The value in this field has the sub second representation of time, with an accuracy of 0.46 ns. When TSCTRLSSR is set, each bit represents 1 ns and the maximum value is 0x3B9A_C9FF, after which it rolls-over to zero.

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.
