10.19 Microprocessor Interface
Proprietary and Confidential to PMC-Sierra, Inc., and for its Customers’ Internal Use
Document ID: PMC-2010883, Issue 2
As each message arrives, the CRC-16 and valid bit is checked; if the valid bit is not set the
message is discarded, if it fails the CRC check it is flagged as being in error and an interrupt is
generated if enabled. If the CRC-16 is OK, regardless of the valid bit, the Page Link, User and
Aux bits are passed on immediately. If the FIFO erroneously overflows, an interrupt is generated.
The Microprocessor Interface block provides normal and test mode registers, and logic required
to connect to the microprocessor interface. The normal mode registers are required for normal
operation, and test mode registers are used to enhance testability of the SBSLITE.
