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: On PIC18(L)F2X/4XK22 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 (FOSC = 64 MHz or 48 MHz) is supported until a BOR occurs. This
is valid although V
DD may be below the minimum voltage for this frequency.
