If a scheduled communication to the TMP468 fails, then PF Alert D[TMPC] is set and a retry occurs at the next scheduled interval. Each time a communication fails, the internal TMP468 fail counter increments, and if the counter reaches the TMPC Threshold, then the device enters PF mode and sets PF Status D [TMPC] if Enable PF D [TMPC] is set. The internal TMP468 fail counter is decremented after each TMPC Delay time.
