Voltage reference

Hi all,

I'm working on a project with a STM8AL, in the reference manual I found this section :

14.3.17 Internal reference voltage conversion
The internal reference voltage is internally connected to the VREFINT channel. This analog
input channel is used to convert the internal reference voltage into a digital value.
The VREFINTON bit in the ADC_TRIGR1 register must be set to enable the internal
reference voltage. This reference voltage must be enabled only if its conversion is required.
The internal reference voltage is factory measured and the result of the ADC conversion is
stored in a specific data address: the VREFINT_Factory_CONV byte represents the LSB of
the VREFINT 12-bit ADC conversion result while the MSB have a fixed value: 0x6.


But I can't find anything about the value of this VREFINT_Factory_CONV address. Is there someone knows where I can find it ?

Thanks.
