Other Parts Discussed in Thread: BQ27320
Hello TI!
I am implementing a driver for the BQ27320 and have trouble understanding the format of the FW VERSION control subcommand.
I am sending FW_VERSION subcommand (0x0002) to the MAC register (0x3E), which gives response size (MACDataLen @0x61) of 15 bytes.
How does this correspond to the command description in the reference manual (SLUUBE6A, March 2018), section 2.1.3?
How many bytes should I expect and how to interpret them?
P.S. using the same function, I can successfully execute the DEVICE_TYPE subcommand (0x0001) which returns expected number of bytes and correct value (0x0320), indicating that the procedure should be correct?
