The Interrupt Source register reflects the source of pending interrupts.
• UAA Set = Interrupt pending in the UAA register.
• ETXRXA Set = Interrupt pending in the ETXRXA register.
• RBLA Set = Interrupt pending in the RBLA register.
• RBPA Set = Interrupt pending in the RBPA register.
• RBRA Set = Interrupt pending in the RBRA register.
• RALA Set = Interrupt pending in the RALA register.
• RAPA Set = Interrupt pending in the RAPA register.
• RARA Set = Interrupt pending in the RARA register.

This register contains the interrupt enables for the corresponding alarms in the IS register. Set = interrupt

The Link Status and Control register is the general control for the transmit and receive links.
• RDSLOV Remote Descrambler Lock Override. When clear, this allows the transmitter/assembler to
automatically send Idle cells containing the Scrambler sequence whenever the remote descrambler falls out
of lock. This determined by either the RARDSLK bit or the RBRDSLK bit clear, depending on the Active
receive port defined by the LBA bit. This action should force the remote descrambler back into lock. Traffic
cells are not transmitted during this action until remote descrambler lock is achieved. If the RDSLKOV bit is
set then the actual status of the remote descrambler (RARDSLK or RBRDSLK) is ignored and it is assumed
that the remote descrambler is locked and therefore normal traffic cells are transmitted.
• SCDIS Transmit scrambler disable. When set the scrambler is disabled and unscrambled data is transmitted.
When clear the scrambler is active and transmitted data is scrambled.
