BIT DESCRIPTION
Octets Transmitted OK is a count of data and padding octets of
frames successfully transmitted. OctetsTransmittedOk will wrap
around to zero after reaching 0xFFFFFFFF. See IEEE 802.3 Clause
30.3.1.1.8.
An UpdateStats interrupt (UpdateStats bit within the IntStatus
register) will occur when OctetsTransmittedOk reaches a value of
0xC0. OctetsTransmittedOk is enabled by writing a logic 1 to the
StatisticsEnable bit in the MACCtrl1 register.
A read of OctetsTransmittedOk also clears the register.

BIT DESCRIPTION
Single Collision Frames is a count of the number of frames that are
involved in a single collision, and are subsequently transmitted
successfully. SingleCollisionFrames will wrap around to zero after
reaching 0xFF. See IEEE 802.3 Clause 30.3.1.1.3.
An UpdateStats interrupt (UpdateStats bit within the IntStatus
register) will occur when SingleCollisionFrames reaches a value of
0xC0. SingleCollisionFrames is enabled by writing a logic 1 to the
StatisticsEnable bit in the MACCtrl1 register.
A read of SingleCollisionFrames also clears the register.
