Hi Team,

If a standard WD is needed, device will ignore the connected component at WRS, or the pin must be leave as floating? Thanks.

Hi Hailiang,

The pin status is ignored for the standard watchdog. You can ground the pin in this case.

Nick

Hi Nick,

Customer connect a 10k ohms to ground. It looks ok, right? Or it is recommend to ground / connect a 0 ohm to ground?

Hi Hailiang,

Sorry, I was on vacation until today. The 10kohm pull down resistor is fine to leave there, but they could get rid of it and ground the pin if they wanted to save some money and board space.

Regards,

Nick
