'12C508 Internal Reset Question'

Hi Gang,

Maybe this is best left for the Microchip people, but I am developing an
application for the 12C508 and I wanted to use all six pins for I/O.

This means that GP3/_MCLR is configured as an input and "Internal _MCLR" is
set in the Configuration fuses.

The problem comes from the application in that sometimes this line will be
low on power-up.  When this occurs, the 12C508 seems to be held in reset
until the line goes high.


Is there any way around this (other than putting this input on another pin
and making sure the reset is always high at power up)?

TIA,

myke
