+description: |
+  The System Timer Module supports commonly required system and
+  application software timing functions. STM includes a 32-bit
+  count-up timer and four 32-bit compare channels with a separate
+  interrupt source for each channel. The timer is driven by the STM
+  module clock divided by an 8-bit prescale value.
