IEEE 1588-2008 Hardware Assist Receive
Snapshot Taken Output: This signal will pulse
high for eight pclks whenever a timestamp has
been taken on the receive channel. The receive
channel that is monitored is determined by the
control bits in the TS_Test Register.
IEEE 1588-2008 Hardware Assist Transmit
Snapshot Taken Output: This signal will pulse
high for eight pclks whenever a timestamp has
been taken on the transmit channel. The
transmit channel that is monitored is
determined by the control bits in the TS_Test
Register.
