Is there provision in up/down sequence at power on/off to AVcc, Vcc pin?

Latest Updated:03/21/2012

Question:

Is there any prescriptions for up/down sequences at power on/off to the voltage applied to the AVcc pin and the Vcc pin?

Answer:

There is no prescriptions of power-on sequence for AVCC and VCC. Although, a long-term service with the power provided either one of VCC or AVCC will deteriorate the LSI. Power on/off AVCC and VCC at the same time is preferable.
