Reads as a logic 0
ANY COLLISIONS
0 A collision is occurring at one or more of the RIC’s ports
1 No collisions
ANY RECEIVE
0 One of the RIC’s ports is the current packet or collision receiver
1 No packet or collision reception within this RIC
JABBER PROTECT
0 The RIC has been forced into jabber protect state by one of its ports or by another port on the
Inter-RIC bus (Multi-RIC operations)
1 No jabber protect conditions exist
ANY PARTITION
0 One or more ports are partitioned
1 No ports are partitioned
These bits define the configuration of ports 2 to 13 i e their use if the internal 10BASE-T
transceivers or the external (AUI-like) transceiver interface
BUS INVERT
This register bit informs whether the Inter-RIC signals IRE ACTN ANYXN COLN and Management
bus signal MCRS are active high or low
0 Active high
