Notes:
1. The temperature is the junction temperature of the die. The thermal assist unit’s raw output does not indicate an absolute
temperature, but must be interpreted by software to derive the absolute junction temperature. For information about the use
and calibration of the TAU, see Freescale Application Note AN1800/D, Programming the Thermal Assist Unit in the MPC750
Microprocessor.
2. The comparator settling time value must be converted into the number of CPU clocks that need to be written into the THRM3
SPR.
3. Guaranteed by design and characterization.
