Temp Sensor, Internal Reference
_______________________________________________________________________________________ 5
Note 9: This time is defined as the number of clock cycles needed for conversion multiplied by the clock period. If the internal refer-
ence needs to be powered up, the total time is additive. The internal reference is always used for temperature measurements.
