EPSL[7:0]:
SPTB Expected Path Signal Label
The EPSL[7:0] bits contain the expected path signal label byte (C2). EPSL[7:0] is
compared with the C2 byte extracted from the receive stream.
When PSLMODE is low, EPSL[7:0] is compared with the accepted path signal label
extracted from the receive stream. A path signal label mismatch (PSLM) is declared if the
accepted PSL differs from the expected PSL. A path signal label match or mismatch is
declared based upon the following table:
When PSLMODE is high, EPSL[7:0] is compared with the received C2 bytes extracted
from the receive stream. A path signal label mismatch (PSLM) is declared if 5
consecutively received C2 bytes (other than 0x00) differ from the expected PSL. A path
signal label match or mismatch is declared based upon the following table:
