Hi @_L_J_ ,

Actually, TLF35584 supports the time protocol that a low pulse of ERR is longer than the detection time tDET,LF.

Hi @LokeshJaikumar ,

Thank you for your interest in Infineon Semiconductor products and for the opportunity to serve you.
Please go to try the demo code, further, there's an application note (AP32342) illustrating how to service the watchdogs.

Hi @Jeremy_Z ,

Thank you for your reply, i went through the demo code and i have enabled all three services two watchdog and error pin monitoring.

watchdogs is working fine.

error pin monitoring is not working, the FSP pin should be toggled at frequency 10 - 45 khz for valid service , but fault state time should be >=250us which is invalid  and cannot be changed below the value.

can you suggest any idea
