Signal Description
Internal Event Signaling
The Event signaling can either happen synchronously to the main clock (CLK_MAIN), or asynchronously
to it.
Depending on the underlying event, the Event signal can be a pulse with a duration of 1 clock cycle, or a
level signal (similar to a status flag).

Debug Operation
14.2.3.1 Clocks
The EVSYS uses the peripheral clock for I/O registers and software events. When set up correctly, the
routing network can be used also in sleep modes without any clock. Software Events will not work in
sleep modes where the peripheral clock is halted.
