BIT DESCRIPTION
Multiple Collision Frames is a count of the number of frames that are
involved in more than one collision and are subsequently
transmitted successfully. MultipleCollisionFrames will wrap around
to zero after reaching 0xFF. See IEEE 802.3 Clause 30.3.1.1.4.
An UpdateStats interrupt (UpdateStats bit within the IntStatus
register) will occur when MultipleCollisionFrames reaches a value of
0xC0. MultipleCollisionFrames is enabled by writing a logic 1 to the
StatisticsEnable bit in the MACCtrl1 register.
A read of MultipleCollisionFrames also clears the register.

OctetsReceivedOk

R/W
BIT DESCRIPTION
Octets Received OK is the count of the number of data and padding
octets in frames that are successfully received. OctetsReceivedOk
does not include frames received with frames too long, FCS, length
or alignment errors, or frames lost due to internal MAC sublayer
error (i.e. overrun). OctetsReceivedOk will wrap around to zero after
reaching 0xFFFFFFFF. See IEEE 802.3 Clause 30.3.1.1.14.
An UpdateStats interrupt (UpdateStats bit within the IntStatus
register) will occur when OctetsReceivedOk reaches a value of
0xC0. OctetsReceivedOk is enabled by writing a logic 1 to the
StatisticsEnable bit in the MACCtrl1 register.
A read of OctetsReceivedOk also clears the register.
