Hi.

I'm trying to build a zero-components pullup resistor for an open drain
output.  I have plenty of port pins left on the C84.

Somewhere in the data sheet (can't find where) I read the "weak pullups" of
PortB are equivalent to 470kohm pullup resistors.  Can I parallel them,
like real resistors?  Ie when paralleling 8x 470kohm, I'd get 58kohm.

Do I get 58kohm with 8 PortB pins in pullup mode?
