Reset pin bypassing

Archiver

I have solved several noise problems with my project (many thanks to all who
responded!!), but am somewhat worried about the reset pin. Do I need to
pull it up with a 1 kOhm resistor to help with noise, or is it pretty much
immune to noise?

Archiver

The RES pin is internally pulled up by a 10k resistor, thus
I think it is pretty much immune to noise. Proper shielding/housing
and GND layout practice is advised however.

Thanks. I missed a pull up in the initial design, and only found it when
going back over it after it was built<G>.

Understand ground layout<G>, we pulse at up to 800 Amps around here<G>.

Many thanks!!
