Josh,

Thanks for your input... What do you mean by tristate?  Is there another
state besides on and off?  Are you saying I do the following:

disable outputs
write W to GPIO
enable outputs

If that is what you are referring to I am not sure that is possible as this
output is PWM and the extra 2 instructions per toggle would cut my possible
rate.
