Shading of rows is to assist in readability of the table.
This is the limit to which VDD can be lowered in Sleep mode, or during a device Reset, without losing RAM data.
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.
