Is the data in the on-chip RAM retained at a reset?

Latest Updated:03/25/2009

Question:

Is the data in the on-chip RAM retained at a reset?

Answer:

With the specified power supply, the data in the on-chip RAM is retained, regardless of a power-on/manual reset.
However, if a power-on/manual reset is input during writing data to the on-chip RAM, the data in the on-chip RAM might be destroyed.
