Chapter 6 . COMMREQ/Data_Init_Comm Programming
Figure 26: Data_Init_Comm to Clear Circuit Fault
6.3.5 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 25), the entry for
3 is one less
than the intended beginning address for the Status Block. When programming a
Data_Init_Comm (Figure 26), the entry for 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 - 6.4.16.
If the COMMREQ requires “n” for the Status Block location, the equivalent Data_Init_Comm will
require “n+1” in its 3 .
Also note that the pop-up window presented in Data_Init_Comm (as shown in Figure 26),
allows the user to scroll through the parameters of the command. This is especially useful
where the command has multiple parameters.
