11.3.8
PSR is a read-only register that can read interface signals from the PHY.
11.3.9
TROCR is a 32-bit counter that indicates the number of frames that were unable to be transmitted
in 16 transmission attempts including the retransfer. When 16 transmission attempts have failed,
TROCR is incremented by 1. When the value in this register reaches H'FFFFFFFF, the count is
halted. The counter value is cleared to 0 by a write to this register with any value.

Reserved
These bits are always read as 0. The write value
should always be 0.
LNKSTA Pin Status
The Link status can be read by connecting the Link
signal output from the PHY to the LNKSTA pin. For
the polarity, refer to the PHY specifications to be
connected.
Description
Transmit Retry Over Count
These bits indicate the number of frames that were
unable to be transmitted in 16 transmission attempts
including the retransfer.
