Generate detailed comments check-box enables saving of the “human-readable” commentary describing the
configuration of each module. An example of the comments generated for the CDM module is on
Preserve user comments check-box, when checked assures the user comments placed after the individual macro
values are not lost when generating the “appconfig.h” file. This options is rarely used as there is typically no need for
the user to manually edit any comments in the “appconfig.h” file.
Generate all register values check-box enables saving of all register values of the selected peripheral modules into
the “appconfig.h” file. When this option is not enabled, only the registers with non-reset values, i.e. those modified in the
GCT, are saved. Omitting the reset-value registers in the “appconfig.h” file can reduce the size of the module initialization
code as those values not defined in the file are not written to the peripheral registers. On the other side, this approach
requires all the modules being configured to be in post-reset state, otherwise the result may be unpredictable. This
option should always be set when compiling the application using the “ROM Image” target. Such applications are
typically invoked by the firmware code which may modify a configuration of some peripheral modules for its own use.
