18.0 Register Description
18.6 INTERRUPT SOURCE — 0x06 IS
Type:
Software Lock: No
Reset Value:
The Interrupt Source register reflects the source of pending interrupts.
18.7 INTERRUPT SOURCE ENABLES — 0x07 ISE
Type:
Software Lock: No
Reset Value:
This register contains the interrupt enables for the corresponding alarms in the IS register. Set = interrupt sources enabled and
Clear = interrupt sources disabled.
18.8 LINK STATUS AND CONTROL — 0x08 LKSC
Type:
Software Lock: Yes
Reset Value:
The Link Status and Control register is the general control for the transmit and receive links.
• 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.
• RDSLOV Remote Descrambler Lock Override. When clear, this allows the transmitter/assembler to automatically send Idle
• SCDIS Transmit scrambler disable. When set the scrambler is disabled and unscrambled data is transmitted. When clear the
• CEN Coset enable. When set then the optional coset x
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.
scrambler is active and transmitted data is scrambled.
When clear the coset is not added to the HEC.
