System Information Module and Trim (SIM)MPC5644A Microcontroller Reference Manual, Rev. 6Freescale Semiconductor 1235Chapter 28System Information Module and Trim (SIM)28.1 OverviewThe System Information Module loads configuration data for the device, and trims data used by variousanalog IP blocks to calibrate current/voltage references or other tunable circuits from flash module testrows.Configuration data is maintained by the System Information Module. Some, but not all, of the data isreadable by the user.28.2 User trim valuesTable 28-1 specifies the MPC5644A microcontroller temperature sensor calibration values from addressoffset 0x00 – 0x3C.NOTEThe SIM base address is 0xFFFE_C000 (same as the temperature sensorbase). The temperature sensor calibration values are available as forread-only access.Table 28-1.
