Add DSL to Offset + 0 in Figure 33-29 and Table 33-23, as shown in the
following:

33.4.10, 33-54

Add the following new section:

33.4.10 Changing IMA Version

A new CPCR command has been added to the IMA microcode to change the IMA version
on-the-fly without software intervention. Use the following procedure:

1. Before issuing the command, the user should initialize the COMM_INFO fields in the

parameter RAM as described in

Figure Table 33-13.

.

2. To issue this FCC command, refer to Section 20.4, “Command Set.” Use opcode 1101 (0xD).

m

3. Wait for the CPCR[FLG] to be cleared by the CPM before issuing a new CP command. Refer

to Section 20.4, “Command Set.”

DCB synchronization lost. This interrupt is issued when a link in a group with IGRSTATE[GDSS] = 11
loses synchronization, and the link enters HUNT state at the IFSM.
