1. The VREFINT_Factory_CONV byte represents the 8 LSB of the result of the VREFINT 12-bit ADC conversion performed in
factory. The MSB have a fixed value: 0x6.
2. The TS_Factory_CONV_V90 byte represents the 8 LSB of the result of the V90 12-bit ADC conversion performed in factory.
The 2 MSB have a fixed value: 0x3.
