+name: BSP_CLOCK_USE_SYSTEMTIMER
+description: |
+  The clock from the ARM timer is derived from the system clock. This clock can
+  change dynamically e.g. if the system goes into reduced power or in low power
+  mode. Thus the clock speed adapts to the overall system performance
+  capabilities. For accurate timing it is recommended to use the system timers.
