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
generate d o scil lat io n fre quen cy. W hen en ter ing b ac kup mod e a c or re spo ndin g er ro r will a ris e. I f timing acc ura cy
is required (for clocks, etc), please bear in mind the above in the program design.
