Miscellaneous I/O

There are four LEDs connected directly to the FPGA and four additional LEDs
connected directly to the DSPs (2 each). For DSP modules the software interface to
the LEDs connected to the FPGA is located in the LED register of the standard
Sundance firmware. Bits 0 and 1 of the LED register control the LEDs designated to
the respective DSP. See Table 5 for details on LED identification.
