2.3 LEDs
The TMS570LS31 HDK board has 19 LEDs. Eight of these LEDs (shown in Table 2-9 ) are under user
control. Those LEDs are controlled and programmed by NHET signals.
LEDs DS2, DS3, DS4, and DS5 indicate the presence of the power (+1.2 V, +5 V, 3.3 V, and 12 V) s on
the board. The LED functions are summarized in
Table 2-9 and Table 2-10 .
