目的：通过软件烧录方式写入OTP配置；

方式：在fullAccess模式下，写入控制指令；

I2C_ReadReg(BATTERY_STATUS, (uint8_t *)&(Registers1.BatteryStatus.StatusByte), 2);// 判断Battery Status 是否是FULLACCESS；

if(1 == Registers1.BatteryStatus.StatusBit.SEC) // 判断是否在FULL_ACCESS mode；
{
I2C_ReadSubRegNoCrc(OTP_WR_CHECK, (uint8_t *)OTP_WR_CHECK_Status, 3); // 判断自检是否完成；

if((OTP_WR_CHECK_Status[0]&0x80) != 0) // Programming OK
{
I2C_WriteSubRegNoCRC(BQ_SUBCOMMAND_ADDR, OTP_WRITE, setting_data, 3); // otp write
}
if((OTP_WR_CHECK_Status[0]&0x80) != 0) // Programming OK
