8.4.1 Continuous Conversion Mode

The TMP127-Q1 always powers up in the continuous conversion mode. Immediately after power up, the TMP127-Q1 temperature register will contain an erroneous code until the first temperature conversion has completed. In the continuous conversion mode, the TMP127-Q1 will run a temperature conversion every 200 ms. To enter continuous conversion mode from the shutdown mode, the user must write XX00h to the configuration register. If user writes XX00h to the configuration register, the continous conversion mode will repeatedly run and the device will continue the conversion period uninterrupted. Repeatedly reading and writing to the TMP127-Q1 will not cause adverse behavior. The temperature register output will update to the latest conversion results when CS is pulled low to start a temperature read.
