Hi,
Here is another new comer to PICs.  I am relatively
new to hardware but not to software.  I used to be
very passionate about electronics but then I went into
software.  I have been writing/managing C++ then Java
Enterprise software projects for the past ten or so
years.  Now I am back to my true passion: electronics.
 Anyway, here is my question.

I have a project using p16f628 where output (open
drain) of a comparator is connected back to CCP1 pin. 
Comparator triggers the capture condition.  CCP1 pin
is also used as PWM output when CCP is in PWM mode. 
The datasheet says, "If the RB3/CCP1 is configured as
an output, a write to the port can cause a capture
condition." How does this work? How can an output read
the pin at the same time?

If the write to output actually works, it will save me
some design effort and components.

Thanks for your help.
