Device Functional Modes (continued)

7.4.1.5 One-Shot Mode (OS)

When in shutdown mode, a single conversion can be performed by writing 11 to MOD bits in the configuration

low-power shutdown mode. A one-shot conversion cycle only consists of active conversion time and no standby

period unlike CC mode. Thus, the duration of a one-shot conversion is only affected by the settings in the AVG

bits. Figure 21 shows a timing diagram for this mode with an AVG setting of 00 and Figure 22 shows a timing

diagram for this mode with an AVG setting of 01. At the end of a one-shot conversion, the Data_Ready flag in

the configuration register is set. The Data_Ready flag is cleared by read of the configuration register or

temperature result register. The state of the Data_Ready flag can also be monitored on the ALERT pin by setting

the DR/nAlert_EN bit in the configuration register.

7.4.2 Therm and Alert Modes

The TMP116 can be used to detect if the temperature has crossed a certain temperature limit or if the device is

within a certain temperature range by using the therm or alert functions built into the device. At the end of every

conversion, the TMP116 compares the converted temperature result to the values stored in the low limit register

and high limit register and sets or clears the corresponding status flags in the configuration register, as described

in this section.
