Drive led blinking by hardware interrupt

Hello all.
Excuse me for my bad English. I have a problem: how I can drive a userled (led on C54x board) blinking by hardware interrupt? Which steps I must do in the *cdb file to control the led by HWI?
Thanks,

The interrupts on the C54xx are all inputs. You need to use an output.
DSP's are typically limited in their output options. The Host Port
interface lines on the C5402 series can be used for IO, but I'd check
their source/sink specs before hooking up a LED to them -- they're
designed to drive a bus.
