S/UNI®-ATLAS-3200 Telecom Standard Product Data Sheet
Preliminary
Pin Name
OCIF_ERR
(A) not used
(B) not used
(C) RPP_ERR
Type
Output
Pin No Function
(C) Error: discard packet. RPP_ERR is used to indicate that the
current packet is in error and should be discarded. RPP_ERR is
only asserted when RPP_EOP is asserted.
RPP_ERR is considered valid only when RPP_VAL is asserted.
(D) TLP_ERR
(D) Error. Packet should be aborted. Will only be asserted when
TEOP is simultaneously asserted; only valid when TENB is
asserted.
OCIF_ADDR[5:0]
I/O
(A) RPU_ADDR[5:0]
Input
(A) PHY address (valid values 0 to 47).
RPU_ADDR indicates the PHYID for which RPU_CLAV is to
respond, and (on the last cycle during which RPU_ENB is
deasserted) indicates the PHYID on which to transfer then next
cell.
The use of these bits is optional. If the UTOPIA Master is not
designed to poll this interface, then the Rx PHY UTOPIA
interface can be made to look like a single-PHY interface via the
SERVEOVRD bit in the RxP Configuration Register. In this case,
S/UNI-ATLAS-3200 will perform weighted-round-robin servicing
on all the PHY queues internally, and CLAV will indicate whether
a cell is available on any PHYID. In this case, these bits should
be tied low.
(B) TLU_ADDR[5:0]
Output
(B) PHY address. TLU_ADDR indicates the PHYID for which
TLU_CLAV is to respond, and (on the last cycle during which
TLU_WRENB is deasserted) indicates the PHYID which the
subsequent cell belongs to.
(C) not used
Input
(C) Unused
(D) TLP_ADDR[5:0]
Output
(D) PHY address (valid values 0 to 47). The TLP_ADDR bus is
used with the TLP_PTPA signal to poll the transmit FIFOs packet
available status.
When TLP_ADDR is sampled on the rising edge of TLP_CLK by
the PHY, the polled packet available indication TLP_PTPA signal
is expected to be updated with the status of the port specified by
the TLP_ADDR address on the following rising edge of
TLP_CLK.
