SDL Interrupt Channel [0—3]. Used to record
various occurrences within the SDL framer. The
bits will generate an interrupt if defined by the
interrupt mask, but the register values here are
independent of the interrupt mask values.
Reserved. These bits must be written to their
reset default value (0x00).
B_Message Reception.
A_Message Reception.
Uncorrectable Special Payload Error.
Indicates occurrence of two or more special
payload errors.
Uncorrectable Header Bit Error. Indicates
occurrence of two or more header errors.
Reserved. This bit must be written to its reset
default value (0).
Single Bit Header Error.
Scrambler Out of Sync. Indicates a scrambler
sync slip.
Framer Out of Sync.
SDL Receive Frame Configuration Register.
Reserved. These bits must be written to their
reset default value (000000000).
Disable Scrambling. When this value is 1, the
SDL framer will not unscramble the data prior to
framing.
Reserved. These bits must be written to their
reset default value (0).
Sync Mode. When bit 4 has a value of 1, then
only one framer is used at all times to frame
SDL data. Normally, this bit is 0, and four
coordinated framers are active simultaneously
to synchronize the scrambler process.
Framer Delta. This register will define the delta
value for the CRC-16 framer.
