Autocalibration consumes ROM and RAM resources and increases start time. Autocalibration does not automatically
select the iDAC Range value. If the Raw Count value after calibration is less than half of the resolution range, you
should increase the iDAC Range or reduce the precharge frequency. Autocalibration works to improve marginally
functional configurations.
3.5.9 iDAC Range
The iDAC Range parameter scales the iDAC current output. For example, selecting 2x will scale the iDAC output to
twice the range
Possible values are 1x, 2x, 4x, and 8x.
3.6 CSA_EMC User Module Low-Level Parameters
The CSA_EMC User Module has several low-level parameters in addition to the high-level parameters. These
parameters are specific to the CSA_EMC sensing method and determine how Raw Count data is acquired from the
sensor.
