preserved. Register space will remain available following a
soft reset.
12.4 PTP RESET
The entire PTP function, including the IEEE 1588 clock, as-
sociated logic, and PTP register space (with two exceptions),
can be reset via the PTP_RESET bit in the PTP_CTL register.
The PTP_COC and PTP_CLKSRC registers are not reset in
order to preserve the nominal operation of the clock output.

Below is a partial list of recommended transformers. It is im-
portant that the user realize that variations with PCB and
component characteristics requires that the application be
tested to ensure that the circuit meets the requirements of the
intended application.
