RCC internal clock sources calibration register 2
| MSITRIM3 | MSI clock trimming for ranges 12 to 15 These bits provide an additional user-programmable trimming value that is added to the factory-programmed calibration trim value MSIRC3[4:0] bits. It can be programmed to adjust to voltage and temperature variations that influence the frequency of the MSI.  |  
| MSITRIM2 | MSI clock trimming for ranges 8 to 11 These bits provide an additional user-programmable trimming value that is added to the factory-programmed calibration trim value MSIRC2[4:0] bits. It can be programmed to adjust to voltage and temperature variations that influence the frequency of the MSI.  |  
| MSITRIM1 | MSI clock trimming for ranges 4 to 7 These bits provide an additional user-programmable trimming value that is added to the factory-programmed calibration trim value MSIRC1[4:0] bits. It can be programmed to adjust to voltage and temperature variations that influence the frequency of the MSI.  |  
| MSITRIM0 | MSI clock trimming for ranges 0 to 3 These bits provide an additional user-programmable trimming value that is added to the factory-programmed calibration trim value MSIRC0[4:0] bits. It can be programmed to adjust to voltage and temperature variations that influence the frequency of the MSI.  |
