Comparison: COMMREQ vs Data_Init_Comm

Data_Init_Comm is an instruction designed to help programmers set up COMMREQs.
Note that when programming a COMMREQ (Figure 30), the entry for Address+3 is one less than the intended
beginning address for the Status Block. When programming a Data_Init_Comm (Figure 31), the entry for
Address+3 is the actual intended memory location for the beginning address for the Status Block.
This difference applies to all command blocks detailed in the following sections 6.4.1 - 6.4.18. If the COMMREQ
requires "n" for the Status Block location, the equivalent Data_Init_Comm will require "n+1" in its Address+3.
Also note that the pop-up window presented in Data_Init_Comm (as shown in Figure 31), allows the user to
scroll through the parameters of the command. This is especially useful where the command has multiple
parameters.
