â Data in âTypâ 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: Refer to Section 7.8 âUsing the Data EEPROMâ for a more detailed discussion on data EEPROM
endurance.
