8.5.2.2 Communication in Continuous Conversion Mode

Continuous Conversion mode is enabled by writing XX00h to the Mode byte in the configuration register. While in continuous conversion mode, the TMP127-Q1 will output the latest Temperature information on the SIO pin for the first 16 clock cycles. After the 16th falling SCLK edge, the TMP127-Q1 will tri-state the SIO pin and be ready for the Controller to drive the SIO pin to write to the configuration register.

Figure 8-3 shows a diagram of the communication in continuous conversion mode.
