Low Energy Timer (LETIMER) Peripheral API.
This module contains functions to control the LETIMER peripheral of Silicon Labs 32-bit MCUs and SoCs. The LETIMER is a down-counter that can keep track of time and output configurable waveforms.

void LETIMER_Init | ( | LETIMER_TypeDef * | letimer, |

Initialize LETIMER.
Note that the compare/repeat values must be set separately with LETIMER_CompareSet() and LETIMER_RepeatSet(). That should probably be done prior to the use of this function if configuring the LETIMER to start when initialization is completed.
