PCF8563 have a bug with Irq INT?

[jeancolin]

  The INT irq never goes Low of PCF8563 Real time clock. Even  with Alarm with bit AF and AIE = 1  or Timer , bit TF and TIE = 1, I try everything voltage: 3.3v or 5v   pull up resistor 2k; 10k ; 100k; 10M 

Every thing works setting time, Alarm, Timer  except  INT .

Hello Jean,

Are you clearing the interrupt flags at the beginning of your application?

Can you share with me the schematic?

Please make sure the bits TIE and AIE are enabled, otherwise, pin INT will remain high-impedance.
