+ * Description:

+ *   The timer 24-bit value is the 16-bit counter value AND the 8-bit
+ *   prescaler value.  From the caller's point of view the match value is
+ *   the 24-bit timer at the timer input clock frequency.

+ *   When counting down in periodic modes, the prescaler contains the
+ *   least-significant bits of the count. When counting up, the prescaler
+ *   holds the most-significant bits of the count.  But the caller is
+ *   protected from this complexity.
+ *
+ * Input Parameters:
+ *   handle - The handle value returned  by tiva_gptm_configure()
+ *   tmndx  - Either TIMER16A or TIMER16B to select the 16-bit timer
+ *
+ * Returned Value:
+ *   The current 24-bit counter value.
