What is the expected status (High/Low) of Port P and S pin when the S12ZVL comes out of reset? I am testing the controller in and around the Low Voltage Assert (2.95V) to Low Voltage De-assert (3.13V) range. I see that when supply voltage exceeds 3.13V,  Port S and P go high momentarily and automatically come down. I am using these port pins as output and they have been initialized to 0 in the code.  

 

Additionally I also observe that at for Supply Voltage between 2.95V - 3.13V, the pin PS3 toggles constantly. What could be the reason for this behavior?
