Hi Team,
I am new to blackfin processor programming...need help from community. where i can find the sample source code for NMI interrupt/handler configuration for watchdog.
Using Blackfin® (ADSP-BFxxx) processor.

Hello Divya/AD Team,
Could you please confirm whether I can make the AD527 NMI pin disable via firmware logic? If yes, then share details, how?
Hi Kalpesh,
No, As per the ADSP-BF52x HRM, NMI (Non Maskable interrupt) - A high priority interrupt that cannot be disabled by another interrupt. There is no register control to disable or ignore it in software. If the NMI pin is asserted, the processor will always take the NMI.
The NMI pin is level-sensitive and should always be pulled to its deasserted state if unused by hardware.
