12description:
13  The System Timer Module supports commonly required system and application
14  software timing functions. STM includes a 32-bit count-up timer and four
15  32-bit compare channels with a separate interrupt source for each channel.
16  The timer is driven by the STM module clock divided by an 8-bit prescale
17  value.
