This question is relevant to all ADuC702x/ADuC712x and ADuC706x parts:
What behaviour should be expected of RSTSTA immediately after powering up the part?
The RSTSTA.0 bit will always be set to 1 after a power up sequence to indicate a POR (Power on reset) reset occured.
However, if an external reset is also asserted at the same time as the Power on sequence, then RSTSTA.3 may or may not be set to indicate that an external reset was also active.
In summary, RSTSTA.3 should only be taken into account after a POR sequence is complete
