can PTA5(reset) pin be used as a output IO - MC9s08qd4

[nal]

muc is MC9s08QD4 
PTA5 connect a 100K resistance to pull down to keep output 0
when I enable pull up in MC9s08qd4 to output 1 ,I donot know it is possible
and I want to know the pull up resistance in PTA5 in mc9s08qd4  10K or other
anyone can tell me
thanks much

Hi Peg

Thanks for your quick reply.

Hi Nal,

PTA5 is input only on a QD4. RTFM, that's what I just did!

To determine the pullup resistor value:
Enable the pullup on an input pin.
Temporarily connect different value external pulldown resistors.
Measure the pin voltage at the same time.
When you get 1/2 Vdd then the external resistor equals the internal one.
From memory on other S08's the value is something like 40k.
