6.3.2 SensorPath BIT SIGNALING

Signals are transmitted over SensorPath using pulse-width encoding. There are five types of "bit signals":

  • Data Bit 0
  • Data Bit 1
  • Start Bit
  • Attention Request
  • Reset

All the "bit signals" involve driving the bus to a low level. The duration of the low level differentiates between the different "bit-signals". Each "bit signal" has a fixed pulse width. SensorPath supports a Bus Reset Operation and Clock Training sequence that allows the slave device to synchronize its internal clock rate to the master. Since the LM95010 meets the ±15% timing requirements of SensorPath, the LM95010 does not require the Clock Training sequence and does support this feature. This section defines the "bit signal" behavior in all the modes. Please refer to the timing diagrams in Electrical Characteristics (Figure 5-2 and Figure 5-3) while going through this section. Note that the timing diagrams for the different types of "bit signals" are shown together to better highlight the timing relationships between them. However, the different types of "bit signals" appear on SWD at different points in time. These timing diagrams show the signals as driven by the master and the LM95010 slave as well as the signal as seen when probing SWD. Signals labels that begin with the label Mout_ depict a drive by the master. Signals labels that begin with the label Slv_ depict the drive by the LM95010. All other signals show what would be seen when probing SWD for a particular function (e.g. "Master Wr 0" is the Master transmitting a Data Bit with the value of 0).
