Legend: Shading of rows is to assist in readability of the table.
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: When BOR is on and BORV<1:0> = 0x, the device will operate correctly at 40 MHz for any V
DD at which the BOR allows
execution.
