#define AVR_ENTER_CRITICAL_REGION ( )

Value:

uint8_t volatile saved_sreg = SREG; \

cli();

This macro will protect the following code from interrupts.

#define AVR_LEAVE_CRITICAL_REGION ( ) SREG = saved_sreg;

This macro must always be used in conjunction with AVR_ENTER_CRITICAL_REGION so the interrupts are enabled again.

#define delay_us ( us ) (_delay_us( us ))

Define the delay_us macro for GCC.

#define F_CPU 11059200UL

Define default CPU frequency, if this is not already defined.

#define INLINE static inline

#define MAIN_TASK_EPILOGUE ( ) return -1;

#define MAIN_TASK_PROLOGUE int

#define nop ( ) do { __asm__ __volatile__ ("nop"); } while (0)

Define the no operation macro.

#define SHORTENUM __attribute__ ((packed))

#define sleep_enter ( ) sleep_cpu()

Define the sleep_enter macro for GCC.
