STR720-EVAL

9/31

If pins 5 and 7 are not used they should be shorted to pins 6 and 8 respectively. Alternatively

the analog inputs can be used directly by removing the shorting and connecting the signal to be

sampled to links 1, 3, 5 or 7, see

Figure 3.

Software controlled LEDs

The (red) LEDs in

Table 3 are software controlled by PIO pins. See the schematic in

Section 4.1 on page 18.
