In order to read data from the TS4956, after the “start” message, the MCU must send and
receive the following data:
send byte with the I2C 7-bit slave address and with the R/W bit set high
receive the data (control register value)
All bytes are read with MSB bit first. The transfer of read data is ended with “stop” message.
When transmitting several data, the data can be read with no need to repeat the “start”
message and the byte with slave address. In this case the value of control register is read
repeatedly.
