ISR

(

ACA_AC1_vect

)

Interrupt handler for analog comparator A channel 1.

This function will handle interrupt on analog comparator A channel 1 and call the analog comparator channel A callback function.

References ac_aca_callback, AC_STATUS_ABOVE, and AC_STATUS_BELOW.

ISR

(

ACA_ACW_vect

)

Interrupt handler for analog comparator A in window mode.

This function will handle interrupt on analog comparator A in window mode and call the analog comparator channel A callback function.

References ac_aca_callback.

ISR

(

ACB_AC0_vect

)

Interrupt handler for analog comparator B channel 0.

This function will handle interrupt on analog comparator B channel 0 and call the analog comparator channel B callback function.

ISR

(

ACB_AC1_vect

)

Interrupt handler for analog comparator B channel 1.
