† Data in “Typ” column is at 5.0V, 25°C unless otherwise stated. These parameters are for design guidance
only and are not tested.
Note 1: These specifications are for programming the on-chip program memory through the use of Table Write
instructions.
2: The pin may be kept in this range at times other than programming, but it is not recommended.
3: Retention time is valid, provided no other specifications are violated.
