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: 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 = 64 MHz) is supported until a BOR occurs. This is valid
although V
DD may be below the minimum voltage for this frequency.
