Q
I am using an ADM6316 supervisor in my circuit. I have the WDI watchdog input
connected to DAI18 of an ADSP-21369. During development, I need to float the
WDI input so the watchdog will not time out. Is it ok to disable the DAI pin
buffer and not enable the internal 22k pull-up?

I've looked at the ADM6313 specifications. The way you planned to disable the
Watchdog during development should work, given the characteristics of the WDI
input. Of course having a 0 ohm resistor (or jumper) to disconnect the input
during development will be ideal so you won't have to deal with code revisions.
