Using Analog comparator Interumpt with IR distance sensor

hello, i’m trying to star an interumpt when the IR send voltage greater then 1,1v (wich is acbg), it means the IR send 1,1v at 54cm so a voltage greater then 1,1v is between 20cm-53cm thats where i want the interupt to occur , from the datasheet i got 3 modes of compar ;Rising (11),failing(10) and change(00) but the problem is that the 3 of them give me the same answer they generate an interumption between 54cm and 150cm and the interumpts stop at 20cm-53cm

#include <avr/interrupt.h>


void setup()
{//i use arduino nano 
pinMode(7,INPUT);
Serial.begin(9600);
ACSR = B01011010; 
//analog interrupt example with the nano
//set the ACSR (analog comparator control and status register)
//ACSR - [ACD, ACBG, ACO, ACI, ACIE, ACIC, ACIS1, ACIS0]
//[ACD: anlog comparator, ACBG: analog comparator bandgap select: AIN1 is applied to positive input
//ACO: analog comparator output, ACI: analog comparator interrupt flag: clear pending interrupt
//ACIE: analog comparator interrupt:enable ,ACIC: analog comparator input capture: disable
//ACIS1: enable for rising edge, ACIS0: enable for rising edge
//ACIS1: disable for toggle, ACIS0: disable for toggle]
}

void loop()
{
}

ISR(ANALOG_COMP_vect)
{
Serial.println("Interrupt Executed!");
}

anyone got an idea

please any help
