I/O port of ADUC7021


I use pin 3 of port 1 (P1.3) on my products and at power up, the port is in high impedance, everything is ok.

Now we received a new reel of aduc7021 and this port (pin 1.3) now emit a glitch at power_up : 2V during 17ms with a pull down of 68Kohm.

My application doesn't work now!

Do you have changed something? Is there is a solution?
