7.2.1
Reference voltage
The ASSP contains a highly sophisticated precision reference voltage. Its typical temperature dependence is a slight parabola shaped curve and is
shown in figure 21. This reference voltage is used mainly for the internal AD-converter, but can also be used for external purposes if the impedance of
the external circuitry is high enough.
The absolute value and its temperature coefficient (TC) is given by the content of the TRR register. This opens the possibility to calibrate the reference
voltage to the optimum absolute value (i.e. 1.28 V) and the TC value to zero thus eliminating fully the production spread.
Writing into subregister TRIMBV of TRR changes the absolute value linearly by 5.1 mV per digit as shown in the following graph and described in full
detail in 7.5.7
Trimming the TC value is similarly done by writing into subregister TRIMBTC. Since the TC trimming is also changing the absolute value it is important
to trim the TC first and then the absolute value.
