Reference Manual
Figure 2–5 shows the schematic connections for the dedicated JTAG programming
header (J59).
Status Elements
The development board include 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
the 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 on the LED while a logic 1 is driven to turn off the LED.
Table 2–7 lists the LED board references, names, and functional descriptions.
