I plan on using the PIC12C508 in an application and have an
external voltage supervisor tied to MCLR for brownout lockup
prevention.

  Problem is that if I configure the 12C508 to use the MCLR pin,
all the I/O ports become weak pullups.

  The data sheet gives sample resistance values for MCLR's weak
pullup (I know it is a really a FET), but are these values the same
for the port pins?  Should I use external pullups just in case?

Thanks for any tips.
Dave
