您参考下面的答复：
The BQ76925 has a base 7 bit address of 0x20, see table 4 of the data sheet. The byte addresses are combined with the device address, so for a write the 8 bit address space would be 0x40 to 0x7E (even only for write).
Remember that the BQ76925 does not have an ADC, it is analog output. On the EVM the MSP430 converts the values from the BQ76925 and transfers them to the PC for display. The mechanism of the control and transfer of the MSP430 are not described, but basically the MSP430 has an I2C register space which is read by the PC. It is not documented in the BQ76925 EVM user guide how the control is provided, or the data assignments.
So any read or write to an address outside the BQ76925 space would be to the MSP430, those values are not documented.
