I use the STM32F103 to communicate with BQ33100 through the SMBus.And the STM32F103 print the data received from the BQ33100 to PC through the USART.
Now,I have some questions below:
1. I want to read the Voltage.So I use the 0x09 command of the SBS COMMANDS list, but I can't recevie the ACK of the SBS COMMAND from BQ33100Image may be NSFW.

.
However, I can receive the ACK after sending the 0x00 command. And the returning data are 00 00.

So I want to know the whole detailed steps about the reading and writting transmitting format or squence which I did't find in the datasheet.
My data transmitting is below:
a. Start
b. Send the Slave Address(0x16) and the write flag
c. Wait the ACK
d. Send the Command Code(0x09)
e. Wait the ACK
2. I want to set the OC Dsg in the flash,the OC Dsg location is defined as: Subclass=1,offset = 11.
My transmitting sequence is below:
a. Start
b. Send the Slave Address(0x16) and the write flag
c. Wait the ACK
d. Send the DataFlashSubClassID Command(0x77)
e. Wait the ACK
But I also can't recevie the ACK(e), what is the correct method for accessing the flash?
3. I didn't find the correct transmitting sequence by using the MAC Command, such as 0x0020.

Thanks for your help!!
