BIT DESCRIPTION
Frames Transmitted OK is a count of the number of frames that are
successfully transmitted. FramesTransmittedOk will wrap around to
zero after reaching 0xFFFF. See IEEE 802.3 Clause 30.3.1.1.2.
An UpdateStats interrupt (UpdateStats bit within the IntStatus
register) will occur when FramesTransmittedOk reaches a value of
0xC0. FramesTransmittedOk is enabled by writing a logic 1 to the
StatisticsEnable bit in the MACCtrl1 register.
A read of FramesTransmittedOk also clears the register.

BIT DESCRIPTION
Frames with Deferred Transmit is a count of the number of frames
that must delay their first attempt of transmission because the
medium was busy. Frames involved in any collisions are not
counted
by
FramesWithDeferredXmission wrap around to zero after reaching
0xFF. See IEEE 802.3 Clause 30.3.1.1.9.
An UpdateStats interrupt (UpdateStats bit within the IntStatus
register) will occur when FramesWithDeferredXmission reaches a
value of 0xC0. FramesWithDeferredXmission is enabled by writing a
logic 1 to the StatisticsEnable bit in the MACCtrl1 register.
A read of FramesWithDeferredXmission also clears the register.
