TMS320C5535 Watchdog Timer Output

Other Parts Discussed in Thread: TMS320C5535

Tech Support,

Does the TMS320C5535 provide any mechanism for driving an output signal based on watchdog timeout?

Thanks,

Mark

    Hi Mark,

    Not really - When the WDT counter expires, a hardware reset is generated...

    You can perform some output after this reset - after execution of the bootloader.

    Or you could look for signals that are toggled by the bootloader - XF or CLKOUT for instance.

    You could even use --reg_config in the boot image to affect some pins before the bootloader completes.

    There is no pin dedicated to WDT timeout, and the RESET pin is an input only.

    Refer to 5.3.1 Watchdog Timer Function in SPRUH87.

    Hope this helps,
    Mark
