About interrupts

Hello,community

Is it possible to check the interrupt status with GPIO interrupt status register (GPIOx_ISR) for both Active HIGH Interrupt from INT7 from GPIO and Combined interrupt indication for GPIO1 signal 0 throughout 15?
Is Active HIGH Interrupt from INT7 from GPIO's Active HIGH high-level sensitive, not rising-edge sensitive?
Is Active HIGH Interrupt from INT7 from GPIO enabled by GPIO interrupt mask register (GPIOx_IMR)?

Best Regards, Goto

Interrupt is configured using GPIOx_ICR1, in the same way as for other interrupts (for example Combined interrupt).

It can be masked by GPIOx_IMR.
