7.0 RIC2A Registers
Interrupt and Management Configuration Register (Page 0H Address 16H)
This register powers up with all bits set to one and must be initialized by a processor write cycle before any events will
generate interrupts.
RIC2A Address Register (Page 0H Address 17H)
This register may be used to differentiate between RIC2As in a multi-RIC2A repeater system. The contents of this register
form part of the information available through the management bus.

Management Interface Configuration
0: All Packets repeated are transmitted over the Management bus.
1: Packets repeated by the RIC2A that do not have Start of Frame Delimiters are
not transmitted over the Management bus.
Interrupt on Partition
0: Interrupts will be generated (RTI pin goes active) if a port becomes Partitioned.
1: No interrupts are generated by this condition.
Interrupt on Collision
0: Interrupts will be generated (RTI pin goes active) if this RIC2A has a port that
experiences a collision (single RIC2A applications,) or contains a port that
experiences a receive collision or is the first port to suffer a transmit collision in a
packet in Multi-RIC2A applications.
1: No interrupts are generated by this condition.
Interrupt on Receive
0: Interrupts will be generated (RTI pin goes active) if this RIC2A contains the
receive port for packet or collision activity.
1: No interrupts are generated by this condition.
Interrupt on Flag Found
0: Interrupts will be generated (ELI pin goes active) if one or more than one of the
flags in the flag array is true.
1: No interrupts are generated by this condition.
Interrupt on Low Count
0: Interrupt generated (ELI pin goes active) when one or more of the Event
Counters holds a value less than 256 counts.
1: no effect
Interrupt on High Count
0: Interrupt generated (ELI pin goes active) when one or more of the Event
Counters holds a value in excess of 49152 counts.
1: No effect
Interrupt on Full Counter
0: Interrupt generated (ELI pin goes active) when one or more of the Event
Counters is full.
1: No effect
