The External Event 2 Snapshot register consists of four 16-bit registers. A rising edge on
the input signal event_2_sig , triggers a snapshot of the System Time into Evnt2_XX_XX
registers and the evs2 bit in Time Sync Event register is set. Polling of the Time Sync
Event register for evs2 can be used to determine when this register is ready for a read.
Reads of the four 16-bit registers can be performed in any order. The evs2 bit in the
Time Sync Event register must be reset by writing a ‘1’ to it in order to snapshot the
system time at the next rising edge of event_2_sig .

The Transmit Snapshot register consists of four 16-bit registers. A Sync frame in master
mode or Delay_Req frame in slave mode triggers a snapshot of the System Time into
Xmit_XX_XX registers and the txs bit in Time Sync Event register is set. Reads of the
four 16-bit registers can be performed in any order. The txs bit in the Time Sync Event
register must be reset by writing a ‘1’ to it in order to snapshot system time at the next
Sync or Delay_Req frame.
