Note:

When a Lithium battery has been selected as the power supply, please note the following points.

There are two modes of use for the lithium battery: Backup mode and Normal mode (backup flag off). In backup mode, the

battery potential is applied directly to the oscillation circuit, whereas in Normal mode only half the battery potential is applied.

Because of the different voltage applied to the oscillation circuit in each mode, there may be a difference in the generated

oscillation frequency. When entering backup mode a corresponding error will arise. If timing accuracy is required (for clocks,

etc), please bear in mind the above in the program design.
