  *
  * Debug options:
  *   IRSMALLD_DEBUG_STATE    - Prints FSM states
- *   IRSMALLD_DEBUG_DURATION - Prints pulse/space/mark intervals' duration
- *   IRSMALLD_DEBUG_TIME     - Prints ISR execution time
+ *   IRSMALLD_DEBUG_INTERVAL - Prints interval's duration between consecutive interrupts (in µs)
+ *   IRSMALLD_DEBUG_ISRTIME  - Prints ISR execution time (in µs)
  * 
  * NOTES:
  * - The usage of debuging functionalities requires a Serial.begin in the setup;
  * - The serial communication speed must be high, to avoid timing errors;
  *   A Baud Rate of 250000 seems to work;
  * - The usage of Serial communications inside an interrupt is not recommended, but 
  *   in this case, it's just a few prints for debuging purposes.
- * - IRSMALLD_DEBUG_TIME mode uses AVR 328p Timer1 hardware specific code;
- *   Results are in micro seconds, assuming a 16MHz clock (Clk Count is divided by 16 to get µs);
+ * - IRSMALLD_DEBUG_ISRTIME mode uses AVR 328p Timer1 hardware specific code;
