I/O Characteristics
Receive Data Output. When the decoder is enabled in 10 bit mode
(ENCBYP* is HIGH and BYTE8/10* is LOW), this output is the tenth bit (MSB)
of the 10 bit decoded and unpacked data character. When the Decoder is
enabled and in 8 bit mode this output is ignored.
When the Decoder is bypassed (ENCBYP* is LOW), RXDATA[9] functions as
the tenth bit of the 10 or 12 bit undecoded receive character.
Received Violation Symbol Indicator. For data accesses with the Receive
FIFO and decoder are enabled (FIFOBYP* and ENCBYP* are HIGH) this
signal is used as an output. It is decoded in conjunction with RXSC/D* and
RXSOC, according to
Special Character codes in the received data stream. For data accesses with
the Receive FIFO disabled and the Decoder enabled, this output indicates a
code word violation detection on the serial inputs.
When the Decoder is bypassed (ENCBYP* is LOW) and in 10 -bit mode
(BYTE8/10* is LOW), RXDATA[10] functions as the eleventh bit of the 12 bit
undecoded receive character. In 8 bit mode this output is unused and is driven
LOW.
RXRVS reports BIST pattern mismatches when RXBISTEN* is LOW.
When accessing the Serial Address Register, this signal is a “read/write”
control input. RXRVS LOW allows the host system to write the Serial Address
Register (RXDATA[9:0] and RXSC/D* are inputs). RXRVS HIGH allows the
host system to read the Serial Address Register (RXDATA[9:0] and RXSC/D*
are outputs).
Receive Start Of Cell. When the Receive FIFO and decoder are enabled
(FIFOBYP* and ENCBYP* are HIGH), this output is decoded in conjunction
with RXSC/D* and RXRVS, according to
specific Special Character codes in the received data stream.
When the Decoder is bypassed (ENCBYP* is LOW) and in 10 bit mode
(BYTE8/10* is LOW), RXDATA[11] is the twelfth bit (MSB) of the 12 bit
undecoded receive character. In 8 bit mode (BYTE8/10* is HIGH) this output
is unused and is driven LOW.
Received Special Character or Data Indicator. For data accesses with the
Receive FIFO and decoder enabled (FIFOBYP* and ENCBYP* are HIGH) this
signal is an output. It is decoded in conjunction with RXSOC and RXRVS, in
accordance with
Character codes in the received data stream. For data accesses with the
Receive FIFO disabled and the decoder enabled, this output indicates that the
parallel output RXDATA[7:0] is a Special Character code.
When accessing the Serial Address Register, this signal is an input that selects
the addressing mode. RXSC/D* HIGH configures the Serial Address Register
for Unicast address matching. RXSC/D* LOW configures the Serial Address
Register for Multicast address matching.
When operated with the decoder bypassed (ENCBYP* is LOW) this pin has
no function.
