SATURN USER NETWORK INTERFACE FOR 2488 MBIT/S
PININV
The parallel incoming data invert bit (PININV) controls the active polarity of the incoming data
stream. When PININV is set high, the incoming data stream is complemented before further
processing by the R8TD. When PININV is set low, the incoming data stream is not
complemented.
DLBEN:
The diagnostic loopback enable bit (DLBEN) controls diagnostic loopback operation. When
DLBEN is set high, serial TeleCombus diagnostic loopback is enabled. When DLBEN is set
low, serial TeleCombus diagnostic loopback is disabled. The loopback involves the
complementary R8TD and T8TE blocks. For example, the T8TE which sources APSO[1] will
be diagnostically looped back to the R8TD which sinks APSI[1].
