Legend: Shading of rows is to assist in readability of the table.  
Note 1: This is the limit to which VDD can be lowered in Sleep mode, or during a device Reset, without losing RAM data.  
2: With BOR enabled, full-speed operation (FOSC = 40 MHz) is supported until a BOR occurs. This is valid although  
VDD may be below the minimum voltage for this frequency.
