Part Number:MSP430F5342
I have read section 1.13.5 (not a problem) however there is some (on my part) of what the calibration value for the reference is based on.
1.13.5 shows this:

1.13.5 Calibration Values
The TLV structure contains calibration values that can be used to improve the measurement capability of
various functions. The calibration values available on a given device are shown in the TLV structure of the
device-specific data sheet.
1.13.5.1 REF Calibration
The calibration data for the REF module consists of three words, one word for each reference voltage
available (1.5, 2.0, and 2.5 V). The reference voltages are measured at room temperature. The measured
values are normalized by 1.5 V, 2.0 V, or 2.5 V before being stored into the TLV structure:
