In Table 30-41, change the description of UTOPIAE to the following:
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).
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.
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."
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.
The first bulleted item should read "Direct polling uses CLAV[3–0] with PHY
selection using ADD[1–0]..."
Replace the first sentence of the second bulleted item with the following:
Single CLAV polling uses Clav and ADD[4–0].
Add a cross-reference to Section 30.10.7, "UNI Statistics Table," to the end of
RxPRTY's description.
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.
In Figure 30-59, the address row should appear as follows:
