The 4th type: the host reading the 3-byte or 6-byte ADC data from the device
In this activity there are two frames that are sent separately. The first frame is identical to sending a
single command, which can be one of the conversion result reading commands. In the second frame,
the device will send back the ADC data (either 3 bytes or 6 bytes depending on the commands) after
receiving the correct Device Address followed by a Read Bit.
