Constant Data Dictionary

Calibration Constants

This section lists the calibrations used by the module. For details on calibration constants, refer to the Data Dictionary for the application.

Program(fixed) Constants

Embedded Constants

All embedded constants whose values are provided in Eng units will be evaluated to the equivalent counts by using the FPM_InitFixedPoint_m() macro within the #define statement.

Local

Global

This section lists the global constants used by the module. For details on global constants, refer to the Data Dictionary for the application.
