SDC_PORTQUALITYMASK
In
SDC Port Quality Mask: indicates, when active, that the SDC Port Quality Bit
should be reset.
SDC_PORTQUALITY
Out
SDC Port Quality: indicates, when active, that the Shared DASL Controller has
detected a minimum eye violation on a port. This violation indicates that one or
more of the DASLs that make up the port is not operating within specification.
Application DASL Off Chip Interface
SERIAL_DATA_IN(0:7)
In
Serial Data Input: Serialized data stream received at the serial link speed
SERIAL_DATA_OUT(0:7)
Out
Serial Data Out: Serialized data stream generated at the serial link speed

(16:23) Reserved. All bits are set to zero.
(24:31) Status Count Input - Used in conjunction with the Status Count Output
field of the SDC Status Register to create a watchdog mechanism.
The DASL Controller will increment this field by one and place the
result in the Status Count Output field of the SDC Status Register.
SDC_DEBUGDATA_IN(0:31)
In
Contains the SDC Debug write data. The data is validated by an active Debug
Register Enable with a write command.
SDC_DEBUGADDR(0:15)
In
Contains the SDC Debug address for read and write commands. The address
is validated by an active Debug Register Enable with a read/write command.
