    Hi, Vish

        For Question 1

        When the gauge is in Shutdown mode, you have to apply a voltage between Pack+ pin and Pack- pin no matter how long it has been stayed in shutdown mode.

        To avoid the battery to go to sleep mode, you can the SLEEP bit in DA Configuration register in Dataflash.

        For Question 2

        I think you are asking how to read RSOC from the gas gauge via SMBUS command. To read the RSOC

        You can read the data from the register 0x0D from the device with SMBUS address 0x0b(7 bit address).
