When the TMP43x are in shutdown mode (SD = 1 in the Configuration Register 1), a single conversion on both channels is started by writing any value to the One-Shot Start Register, pointer address 0Fh. This write operation starts one conversion; the TMP43x return to shutdown mode when that conversion completes. The value of the data sent in the write command is irrelevant and is not stored by the TMP43x. When the TMP43x are in shutdown mode, an initial 200 ps is required before a one-shot command can be given. (Note: When a shutdown command is issued, the TMP43x shut down immediately, aborting the current conversion.) This wait time only applies to the 200 ps immediately following shutdown. One-shot commands can be issued without delay thereafter.
