I2C Communications Overview (Cont’d)
Figure 3 - I2C Communication Diagram
Figure 3 illustrates the sequence of signals set by both the host and the sensor for each command. Note that for the Da-
taRead command, the host has the option of responding to the second or third bytes of data with a NACK instead of ACK.
This terminates the data transmission after the pressure data, or after the pressure data and upper byte of temperature,
have been transmitted. See Figure 6 for the I2C timing details.
1. Start All ( to wake sensor from Sleep mode, Zero ADC, read Temperature and read Pressure )
Set by bus master: - - - - I ST A6 A5 A4 A3 A2 A1 A0 R
SP I
Set by sensor: - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - A
2. Start Pressure ( to wake sensor from Sleep mode and read Pressure only )
Set by bus master: - - - - I ST A6 A5 A4 A3 A2 A1 A0 W
SP I
Set by sensor: - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - A
3. Read Data ( with examples of reading pressure, pressure plus 8 bits of temperature and pressure plus 12 bits of temperature )
Set by bus master: - - - - I ST A6 A5 A4 A3 A2 A1 A0 R
A
Set by sensor ( pressure plus status ): - - - - - - - - - - - - - - - - - - - - A D31
… D24
D23 … D16
…then, one of the following:
a) Set by bus master, to stop transfer after pressure data received: - - - - - - - - - - - - - - - - - - - - - - - - N SP I
--OR--
b) Set by bus master, to stop transfer after first temperature data byte received: - - - - - - - - - - - - - - A
N SP I
Set by sensor ( high order 8 bits of temperature ): - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
D15
… D8
--OR--
c) Set by bus master, to stop transfer after last temperature data byte received: - - - - - - - - - - - - - - A
A
N SP I
Set by sensor ( all 12 bits of temperature plus padding bits ): - - - - - - - - - - - - - - - - - - - - - - - - - - - D15
