The charger supports battery-charger commands that use either Write-Word or Read-Word protocols, as summarized in Section 8.5.1.7. The I²C address is 6Bh(0b1101011) consist of 7 bits. Adding read(1b) and write(0b) to the end of address 7bits, the total 8bits data format address should be D6h (1101011_0 for write)/D7h(1101011_1 for read). The ManufacturerID and DeviceID registers are assigned to identify the charger device. The ManufacturerID register command always returns 40h.
