2.3.3 Measurement Cycle

The complete measurement cycle is controlled by the CMC. Depending on EEPROM settings, the multiplexer (MUX) selects the following

input signals in a defined sequence:



Temperature measured by external diode or thermistor, internal pn-junction, or bridge





Pre-amplified bridge sensor signal

The cycle diagram in Figure 2.2 shows the basic structure of the measurement cycle. The bridge sensor measurement count can be

configured in EEPROM for a value within n=<1,31>.

After power-on, the startup routine is processed, which performs all measurements needed to acquire an initial valid conditioned sensor

output. After the startup routine, the normal measurement cycle runs.

Note: The “CMV,” “SSC/SCC+” and “SSC/SCC-” measurements are always performed in every cycle independent of the EEPROM

configuration.
