- * \brief General-purpose input/output
- *
- * This module defines macros for input/output pins of microcontroller.
- * Pin is specified with SET and PIN. SET is letter and PIN is number. Combination
- * of SET and PIN specifies hardware pin. You can find it in documentation.
- *
- * To use this module:

- * #include "avr-ioe/GPIO.h"
