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.

(Note)
There are two operation modes, back-up mode (back up flag on) and normal mode (back up flag off), in Li battery specification. In normal operation mode, the internal circuit of CPU is operated on 1/2 of Li battery voltage (it can be monitored as external capacitor voltage of voltage step down circuit). The power consumption can be saved in normal mode operation. However, the large current flown into/from the buzzer output or output port will generate a voltage drop-down and it might be a cause of abnormal CPU operation. If the microcontroller has to drive a large current, switch the CPU into the back up mode before driving the current. CPU consumes the relatively large current in back up mode. When the Li battery voltage has recovered, you should change the CPU into the normal mode. CPU is in the back up mode at reset.

[Note] These specified value herein are based on the QIP48E packaged parts. The specification for the die is basically the same as the one for package part. However, it will be affected by the many factors such as the mounting board, bonding pressure, cover up epox etc. Therefore the value specified here are only applied in Ta=25C2C operating temperature range.
