33.4.7.1, 33- 47 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).

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.”
