Measurement Registers
Measurement results are reported in pairs of values and decisions. Measurement values are 32 bits wide
and decisions are 8 bits wide.
The measurement ID defines the register address of each pair. The register address of the first word can
be calculated as (1000 + 3 * ID). For example, a measurement with ID set to 4 can be read from registers
1012 (high word) and, 1013 (low word), and the decision at 1015.
In Profile mode, the measurement results are updated after each profile is processed. In Surface mode,
the measurement results are updated after each discrete part has been processed.
