9S12E - Can you drive the external reset pin with software?

Due to the EOL of the Intel 87C196KC, I am redesigning our controllers with the MC9S12E64.  In our application, the 87C196KC was the reset master in our multi-processor system.  I need a way of driving the external reset pin based on various conditions.
 
I believe I can generate an immediate reset by enabling the COP watchdog and then writing garbage (not 0x55 or 0xAA) to the ARMCOP register.  Does this also drive the external reset pin?
 
Thanks -
