On CY8CMBR3116-LQXIT is the pull-up on HI/BUZ/GPO7 mandatory ?
When HI/BUZ/GPO7 is used as inetrrupt (Active LOW) is a Floating output when HIGH ?
Or the pull-up is to avoid false triggering when powering up the device ?

Hi frro_3974886
Yes, a pull up is mandatory on the HI line. The default configuration of the pin is open drain drives low. Hence, it is pulled LOW to indicate an interrupt to the user, but is left floating otherwise.
Hence, a pull up is mandatory.
Thanks,
Hari
