This section describes the CrossWorks Tasking Library which will be subsequently
referred to as the CTL. The CTL provides a multi-priority, pre-emptive,
task switching and synchronisation facility. Additionally the library provides timer,
interrupt service routine and memory block allocation support.

Overview
- Describes the principles behind the CTL.

-
Event sets
- Describes what a CTL event set is and how it can be used.
