30.10.7, 30-84 In Table 30-41, change the description of UTOPIAE to the following:
30.12.1, 30-87 Add the following at the beginning of the section:
Cell transfer on an ATM device (with single or multiple PHYs) uses cell-level
handshaking as defined in the UTOPIA standards. The FCC does not pause cell
transmission by the PHY and does not stop receiving cells from the PHY.
30.12.1, 30-87 In Figure 30-57, “UTOPIA Master Mode Signals,” replace “TxCLAV[3–0]” with
“TxCLAV[3–0]/TxClav” and “RxCLAV[3–0]” with “RxCLAV[3–0]/RxClav.”
30.12.1, 30-87 In Table 30-44, make the following additions:
Add “/TxClav” to “TXCLAV[3-0]”
Add “/RxClav” to “RXCLAV[3-0]”
Add a cross-reference to Section 30.10.7, “UNI Statistics Table,” at the end of
RxPRTY’s description.
30.12.1.1, 30-88 The first bulleted item should read “Direct polling uses CLAV[3–0] with PHY
selection using ADD[1–0]...”
30.12.1.1, 30-88 Replace the first sentence of the second bulleted item with the following:
Single CLAV polling uses Clav and ADD[4–0].
30.12.2, 30-89 Add a cross-reference to Section 30.10.7, “UNI Statistics Table,” to the end of
RxPRTY’s description.
30.12.2, 30-89 Add the following to the beginning of the section:
In UTOPIA slave mode (single or multiple PHY), cells are transferred using
cell-level and octet-level handshakes as defined by the UTOPIA L2 standard. The
FCC allows cell transfer to be halted or paused. If the master negates TXENB
, the
cell that the FCC is transmitting is halted. If the master negates RXENB, the cell
that the FCC is receiving is paused. Note the following restriction on halting a cell
transfer: there cannot be a halt immediately before the transfer of the last data
word. There is no restriction on pausing a cell transfer.
30.13.2, 30-91 In Figure 30-59, the address row should appear as follows:
0x00 UTOPIAE Hword Counts cells dropped as a result of UTOPIA/ATM protocol violations.
Violations include the following:
1. Parity error
2. HEC error
3. Invalid timing of RxSOC.
If RxClav is asserted for the selected PHY, RxSOC should be asserted the
cycle immediately following the assertion of RXENB
. A violation occurs if
RxSOC is not asserted at that time (that is, it is late or is missing).
