51  * @details This module controls the debug LED that is directly connected to a
52  * MCU pin. It is used to indicate basic operation states.
53  *
54  * * During startup the LED is enabled continuously.
55  * * Once the startup is complete the LED should be called with
56  * #LED_SetToggleTime() in order to indicate whether the BMS has
57  * started normal operation (#LED_NORMAL_OPERATION_ON_OFF_TIME_ms,
58  * slow blinking pattern) or if it is in an error state
59  * (#LED_ERROR_OPERATION_ON_OFF_TIME_ms, fast blinking pattern).
60  * * #LED_SetToggleTime() can be called anytime the indicated pattern
61  * shall change.
