Functions
Mapping functions
Functions for mapping value to pins. This functions takes value and list of pins for out mapping. Do not call it directly. Use eppl_avr8_mapOutToOnePort macro, that counts number of pins for mapping and calls right function.
static void	eppl_avr8_mapOutToOnePort1 (uint8_t *pout, uint8_t port, uint8_t val, uint8_t flags, eppl_pin_t pin1) __attribute__((always_inline))
