Timestamp_Addend
This register value is used only when the system time is configured for
Fine Update mode (TSCFUPDT bit in Register 448). This register content is added to a 32-bit accumulator in every clock cycle (of clk_ptp_ref_i) and the system time is updated whenever
the accumulator overflows.
