how can I read data from bq34z100?

hi. I have a question.

How can I read current data(0x0018) from bq34z100?

I tried to read current of bq34z100 using a micom. but I can't read this current.

I know that current is I2C 2 byte. I can read Average current easily and I know that Average current is 1byte.

I tried to do like under example. please give me advice

exaple)

I2C_write(oxaa);

I2C_write(ox00);

I2C_write(ox18);

I2C_write(oxab);

current data=I2C_read(1);

I2C_stop();
