Overview

Overview

The TIMER APP provides accurate hardware timer using one timer slice of CCU4 or CCU8 peripheral. And provides provide the functionality below:

1. Continuous event generation for a given time interval.
2. Generates more accurate delay using Hardware timer.
3. Sets the desired time interval at runtime(in terms of micro-seconds).
4. Connection of timer interval event to other peripherals as a trigger source or for interrupt generation(using the DAVE HW Signal Connections)

Figure 1 : Overview of TIMER APP

The figure above shows the functional overview and use cases of the TIMER APP.

Figure 2 : Hardware and Software connectivity of TIMER APP

The figure above shows the layered architecture of the TIMER APP in DAVE™. XMC controllers provide the CCU4 or CCU8 module. Each module is having four 16-bit timers. The LLD layer provides abstraction for these hardware modules. The TIMER APP uses CCU4 or CCU8 and GPIO LLDs and other dependent APPs like GLOBAL_CCUx(x = [4,8]) and CLOCK_XMCx(x = [1,4]) for the functionality.
