Note 1:
This is the limit to which V
DD
 can be lowered in Sleep mode, or during a device Reset, without losing RAM 
data.
2:
On LF devices with BOR enabled, operation is supported until a BOR occurs. This is valid although V
DD
 
may be below the minimum rated supply voltage.
3:
With BOR enabled, full-speed operation (F
OSC
 = 48 MHz) is supported until a BOR occurs. This is valid 
although V
DD
 may be below the minimum voltage for this frequency.
