In the schematic of Arduino Due, the Master_reset signal is connected to the 3.3V through a capacitor. It seems that this design has some issue: it has the potential effect on the stability of the system.
Regularly, the reset circuit consist of a resistor (about 10K), a capacitor (about 0.01uF) ,and a button switch.

I don't know why Due use that design. Anybody has some idea about that?

There are several resistors, and several chip pins, connected to MASTER-RESET, which provide more than enough "leakage" to charge the reset capacitor.  There is absolutely nothing wrong with the existing circuit.

Thank you very much for your reply!
Before, I was concerned about the charge of the reset capacitor.
