2.3 Writing Addresses
Following a start condition, writing to slave address 0x8A initiates access to subaddresses. Alternative slave
address 0x88 must be written if the ALTADDR pin is high.
2.4 Reading Information
Following a start condition, writing 0x8B initiates the read-back sequence, during which 8 bits of information
can be read from the SDA pin, MSB first. Alternative address 0x89 is required if the ALTADDR pin is high.
The first three bits indicate the part type (Bt864A or Bt865A). The lower five bits indicate either the version
number or the status bits.
