In ADSP-2137x datasheet there is written:
Two general-purpose timers can generate periodic interrupts
and be independently set to operate in one of three modes:
• Pulse waveform generation mode
• Pulse width count/capture mode
• External event watchdog mode
How does work the "External event watchdog mode" ?
There is nothing written about "External event watchdog mode" in Programming Reference, as well as in Hardware Reference.
Is there some application note about how to create a software/hardware Watch Dog on SHARC DSP?
Does someone has a good idea how to create a software Watch Dog with a very small core load and as small as possible registers affections?
