7.6.1.6 One-Shot Start Register

When the TMP451-Q1 device is in shutdown mode (SD = 1 in the configuration register), a single conversion is started by writing any value to the one-shot start register, pointer address 0Fh. This write operation starts one conversion and comparison cycle on both the local and the remote sensors. The TMP451-Q1 device returns to shutdown mode when the cycle completes. The value of the data sent in the write command is irrelevant and is not stored by the TMP451-Q1 device.
