WebFeb 1, 2024 · And because the code only toggles a LED if the interrupt flag for pin 13 is pending, it won't be pending any more when HAL code has cleared it. If HAL executes your user callback, it means the interrupt was pending and cleared to catch the next interrupt before the callback for current interrupt is executed. New info: WebThe I flag is a global interrupt enable/disable bit. All of the interrupt sources are gated with the I flag. If the I flag is set, none of the interrupts will be seen by the processor hardware. This allows the programmer to … The Interrupt flag (IF) is a flag bit in the CPU's FLAGS register, which determines whether or not the (CPU) will respond immediately to maskable hardware interrupts. If the flag is set to 1 maskable interrupts are enabled. If reset (set to 0) such interrupts will be disabled until interrupts are enabled.
