+/*******************************************************************************
+ * MSP432 Clock System - HFXT Startup
+ *
+ * Description:
+ *
+ * HFXTAL:
+ * Starts the 48MHz crystal attached to HFXTIN/HFXTOUT
+ * Sources MCLK from the crystal
+ *
+ * LFXTL:
+ * Starts the 32khz crystal attached to LFXTIN/LFXTOUT
+ * Sources AMCLK from crystal
+ *
+ * Internal DCO:
+ * Starts the DCO
+ * Sources SMCLK from DCO
+ *
+ * Blinks an LED using SysTick (which is sourced from MCLK).
+ *
+ *
