7..0 BroadcastFrames-
ReceivedOk
This statistic counts the number of frames that are successfully
received and are directed to the broadcast group address. This does
not include frames received with frame-too-long, FCS, length or align-
ment errors, or frames lost due to internal MAC error. This is a 8-bit
counter and will wrap around to zero after reaching ffh. An UpdateStats
interrupt will occur, if enabled, after the counter counts through c0h.
