Detailed Description

TLV entry for TAG_ADC10_1 and TAG_ADC12_1 on 2xx MCUs

These are ADC gain and offset calibration constants, as well as constants for the internal temperature sensor. The tag values are not defined on all MCUs, and the observed value is 8 on some and 0x10 on others. The address of sBSP430tlvADC::cal_adc_gain_factor is fixed at 0x10DC.

When processing a 2xx descriptor table, it is reasonable to assume that any tag that is not TAG_DCO_30 nor TAG_EMPTY corresponds to an ADC structure.
