9:8 RESERVED
RO
7:0 Idle Error Count
RO
Cumulative count of the errors detected when the receiver is receiving idles.
These bits are reset to all zeroes when the error count is read by the
management function or upon execution of a hardware reset, software reset,
or logical reset. This field is held at all ones in case of over-flow.
This field can be used to trigger an interrupt upon overflow. Refer to Section
3.5, "Interrupt Management," on page 21 for additional information.
