UTOPIA Interface Registers
R_UICNF—Receive UTOPIA Interface Configuration ((000)70H)
This register configures the receive UTOPIA interface features that are common to the four
channels.
Name
51/155/622/2488 Mbit/s SONET/SDH Cell/Packet Interface — Intel IXF6048
RcvVal2Cnf configures under which conditions the reading in the
receive interface is blocked. When RcvValCnf = '0', reading is
never blocked thus RcvVal2Cnf is only taken into account when
RcvValCnf = '1'. In this case:
if RcvVal2Cnf = '0' then reading is blocked after an EOF is read or
the FIFO is empty
if RcvVal2Cnf = '1' then reading is only blocked after an EOF is
read
RcvATMHEC is used in 8-bit mode (RcvUWidth = '00') to select the
information stored in the extra byte, when an extra byte is passed
through the UTOPIA interface (RcvCellStruct = '1' in register
R_UICHCNF):
'1' = The received HEC is passed as the extra byte.
'0' = Two status bits are passed. Bit 0 indicates whether the header
was error free. If bit 0 is a '1' (meaning that there were errors in the
header), then bit 1 indicates whether the error is single (bit 1 = '0')
or multiple (bit 1 = '1').
In 16- or 32-bit modes, both HEC and status are copied in the extra
word (when RcvCellStruct = '1'). In these modes bits 15:8 contain
the received HEC and bits 1:0 contain the status with the same
meaning as explained for 8-bit mode.
RcvSmallMem reduces the size of the receive UTOPIA interface
FIFO memory used by channel #0:
'0' = Channel #0’s receive FIFO size is 16-Kbyte.
'1' = Channel #0’s receive FIFO size is 2-Kbyte.
RcvSmallMem can be used to force identical behavior in all four
channels.
RcvTestOEn configures whether the unused signals, resulting from
the interface configuration, are set to high impedance:
'0' = Unused signals in the interface (POS signals when configured
in ATM mode or signals used only in quad mode when configured
in single mode) are held in high-impedance.
'1' = Unused signals, determined by the interface configuration, are
not held in high-impedance.
RcvValCnf configures how the RXVAL output is used.
'0' = The reading is never blocked. RXVAL is deasserted when
attempting to read an empty FIFO. In this case, the read command
is disregarded.
'1' = Apart from RXVAL being deasserted when attempting to read
an empty FIFO, the reading is blocked under the conditions
configured in RcvVal2Cnf. When the reading is blocked, RXVAL is
also deasserted and all the read commands are disregarded until
the port is deselected and reselected.
