2.5.1.1 OTHER LOOP-BACK TESTS. A variety of other loop-back modes may be implemented.
Some modes are accessible through the activation menu while others require a working knowledge of the
SCP registers and are accessed through the command line interface of the monitor program. Refer to
Figure 2-8 and the text that follows for a description of some of these loop-backs. Refer also to the
MC145572 data book loop-back section. The menu items referred to are for the combined NT/LT mode.
