8.5
The evaluation board can be powered with a 2.4 to 5 V lithium battery.
The battery needs to be inserted in the correct way.
When connected to the motherboard the evaluation board is automatically powered by the motherboard, the battery or
external power supplies are bypassed.
The on-off button allows the user to the switch between the battery supply and the external source supply.
When the on-off button is set to external source supply, the battery is not subject to discharge.
8.6
To operate the microcontroller with an external oscillator connected to the OSCin pin, first remove the “external clock
source” jumper on the socket board. Once completed, connect the external oscillator to the header on pin “OSCIN”.
8.7
This enables users to restart the program.
When the power supply is turned off and on, the power on reset feature can be disturbed by the time of the Vreg
capacitor discharge (Vreg capacitor = 1uF).
To ensure a better start-up of the chip, it is advised to use the reset button in order to ensure the reset functionality.

On all the future versions of daughter boards there will be different jumper configurations. However there are
some common jumpers that will be described in the table below.
*Note that when you’re using the EEPROM, you must disable the PB4 and PB5 LED’s.
When you’re using a battery supply, it’s suggested to disable the LEDs.
