LED Setting
The SMT361 has 9 LEDs.
LED D6 always displays the state of the FPGA DONE pin. This LED is off when the
FPGA is configured (DONE=1) and on when it is not configured (DONE=0).
This LED should go on when the board is first powered up and go off when the FPGA
has been successfully programmed. If the LED does not light at power-on, check that
you have the mounting pillars and screws fitted properly. If it stays on, the DSP is not
booting correctly.
Four of the remaining LEDs can be controlled with the LED register. Writing 1 will
illuminate the LED; writing 0 will turn it off.
