Symbol Counter Compare 1 interrupt callback function.

This function is called when a compare match has occured on channel 1 of symbol counter. Compare match occurs on end of sleep period

Symbol CounterCompare 2 interrupt callback function.

This function is called when a compare match has occured on channel 2 has occurred CMP2_INT_CHK_PIN is set to LOW. Compare match occurs on end of active period

static void example_cmp3_int_cb ( void  )

static

Symbol Counter Compare 3 interrupt callback function.

This function is called when a compare match has occured on channel 3 of symbol counter and toggles CMP3_INT_CHK_PIN. CMP2_INT_CHK_PIN is set HIGH. Compare match occurs at the end of every beacon interval.
