This page describes each of PXA Clocker options.

PXA Clocker global options, accessible through the Options dialog.

Reactivate on reset
This is a global option. If checked, PXA Clocker will be automatically activated after system reset occurs. This option is disabled in Lite version.

Show Hidden Applications
Global option. If checked, Applications marked as 'hidden' will be managed by PXA Clocker and will be shown in the list in blue text.

Safe peripheral management
This global option that tells PXA Clocker that a safer technics must be used to handle peripheral clocking changes. This is a recommended settting.

Restore default options
Reset all system settings to default and deactivate PXA Clocker. This option also clears all per-appication settings and clears memory card database.

Reset frequency settings
Restores frequency settings for all applications to system default value.

Reset peripheral settings
Restores peripheral clocking settings for all applications to default value for your system (i.e. the value that was in effect before PXA Clocker was activated).

Clear memory card DB
Clears the database that stores settings for applications that reside on memory cards

Set 'skip quit' for PowerRun
Detects PowerRun shortcuts and sets 'Skip Quit' option for them. Skip Quit option is useful for application suites when one application controls a set of other applications. I.e., when you start main application, PXA Clocker adjusts system frequency to the value you specify. Then, when the main application starts another application, PXA Clocker will keep frequency settings for that child applicaton if SkipQuit option is selected. If SkipQuit option is not checked, the frequency will be reverted to a System Default value.
