If written to VME memory in the order given above, these command parameters would be written differently (as shown below) for both types of processors:

Figure 19 Intel Ordering

Figure 20 Motorola Ordering

It becomes apparent when examining the memory displays, that the Command Structures of the RF3880 though divided into a variety of byte, word, and double-word fields, must be considered as a grouping of double-words.

In a Motorola environment, the Parameter Block would remain as graphically represented throughout this manual, and as shown below:

Address		Byte Memory Address
Offset	Offset + 0	Offset + 1	Offset + 2	Offset + 3

00H		Command Identifier - 04030201H

04H	Flags-2 = 01H	Flags-1 = 86H	Addr. Mod = 3EH	Target ID = 02H

08H		VME Memory Address - 005A9320H

0CH		Transfer Count = 00010280H

10H	0 = 2AH	1 = 40H	2 = 0	3 = 08H

14H	4 = F4H	5 = E9H	6 = 0	7 = 02H

18H	8 = 05H	9 = 0	10 = 0	11 = 0
