comparator_init_async

#define comparator_init_async

Value:

do {                                        \
    CMPCR1 = CMPCR1_DEFAULT_VALUE;          \
    CMPCR2 = CMPCR2_DEFAULT_VALUE;          \
                                            \
    enable_mcu_interrupts();                \
    enable_comparator_interrupt(ANY_EDGE);  \
} while(0)

Comparator init for using interrupts routine.

comparator_start

#define comparator_start

(

)

(bit_set(CMPCR1, CMP_ENABLE_BIT))

Comparator start routine.

Before call this method comparator should be initialized by comparator_init_async() or comparator_init_sync()

comparator_stop

#define comparator_stop

(

)

(bit_clr(CMPCR1, CMP_ENABLE_BIT))

Comparator stop routine.

Before call this method comparator should be started by calling comparator_start()
