We have used AduC7026 microcontroller with DS1233A IC to provide reset. It is observed that sometime controller goes to non-responsive state.  

Please clarify that whether the external reset given by the DS1233A will override the internal reset generated inside the controller (if any).

The reset duration provided by the DS1233A is 350ms.

We have assumed that before the internal reset gets over the external reset is provided and the controller goes to non-responsive state which recovers only putting off and on the controller.
Please clarify the reset the reset sequence and applicability of the external reset IC ?
