In the case of the TMP9R00-SP, SETs were categorized as heavy-ion induced events that create a fully recoverable transient (±1.5°C) on the temperature output. Such variations were monitored and captured in software, and a data point was recorded any time the trigger condition was achieved. All SET data was collected at room temperature with a 70-mm air gap. Events are recorded separately for the local channel and each remote channel.

Initial temperature readings were recorded for the local channel and each remote channel. All device registers were read in 350-ms intervals and the current temperature readings were compared with the initial readings to record all events that exceeded ±1.5°C. To make sure that previous transients were not affecting subsequent register reads, a device reset was issued between each measurement. The TMP9R00-SP registers can be software reset by setting bit 15 of the Software Reset register (20h) to 1. This software reset restores the power-on-reset state to all TMP9R00-SP registers and aborts any conversion in progress.
