RXDATA bus output drivers are enabled when the device is
selected by RXEN being asserted in the RXCLK cycle immedi-
ately following that in which the device was addressed (CE is
sampled LOW), and RXEN being sampled by RXCLK. This
initiates a Receive FIFO read cycle.
Just as with the TXDATA bus on the Transmit Input Register,
the receive outputs are also mapped by the specific decoding
and bus-width selected by the ENCBYP, BYTE8/10 and
FIFOBYP inputs. These assignments are shown in
Table 6. Receiver Output Bus Signal Map
Notes
RXDATA Bus Output Bit
8. When BYTE8/10 is HIGH, received bit order is decoded form the serial stream and presented (MSB to LSB) at RXDATA[7,6,5,4] and RXDATA[3,2,1,0] or
9. When BYTE8/10 is LOW, received bit order is decoded form the serial stream and presented (MSB to LSB) at RXDATA[8,7,6,5,4] and RXDATA[9,3,2,1,0] or
10. First bit shifted into the receiver.
11. When ENCBYP is LOW and BYTE8/10 is HIGH, the received bit order is (LSB to MSB) RXD[0,1,2,3,4,5,6,7,8,9].
12. When ENCBYP is LOW and BYTE8/10 is LOW, the received bit order is (LSB to MSB) RXD[0,1,2,3,4,5,6,7,8,9,11,10].

Receiver Decoder Mode
If the Receive FIFO and Decoder are bypassed, all received
characters are passed directly to the Receive Output Register.
If framing is enabled, and JK or LM sync characters have been
detected meeting the present framing requirements, the
output characters will appear on proper character boundaries.
If framing is disabled (RFEN is LOW) or sync characters have
not been detected in the data stream, the received characters
may not be output on their proper 10-bit boundaries. In this
mode, some form of external framing and decoding/descram-
bling must be used to recover the original source data.
