bq27421 Watchdog Reset

Hi,

I am having an issue with the application example on page 11 in the bq27421-G1 Technical Reference (Literature Number: SLUUAC5). I am able to successfully update the design capacity bytes and I verified this calling the design capacity command (DesignCapacity( ): 0x3c/0x3d). This command returns my new design capacity; however, after about 2 seconds, the device is being reset which causes the design capacity bytes to return to the default values. When the reset happens, the ITPOR bit in the flags register (Flags( ): 0x06/0x07) is set as well as the WDRESET bit (Watchdog Reset) in the CONTROL_STATUS register. If I do not update the design capacity bytes,the watchdog reset does not occur.

Thanks in advance for you help,

Bryan
