Status Elements
The development board includes board-specific status LEDs and switches for
enabling and configuring various features on the board, as well as a 16 character × 2
line LCD for displaying board power and temperature measurements. This section
describes these status and setup elements.
Status LEDs
Surface mount LEDs indicate the various status of the board. A logic 0 is driven on the
I/O port to turn the LED on while a logic 1 is driven to turn the LED off.
Table 2–7 lists the LED board references, names, and functional descriptions.
