The answer is interrupts or exceptions. In short, the interrupt vector table contains addresses ( function pointers) of interrupt service /routines and exception handler functions. The interrupt vector table is a table of memory addresses of interrupt/exception handler routines. In other words, it d...
If a level-triggered interrupt from a peripheral device is enabled and active, but the kernel trap handler cannot immediately run the device's interrupt service routine (ISR) to clear the interrupt, the handler masks theinterrupt at the GPIO pin to prevent the pin from repeatedly causing more ...
the interrupt is enabled when the bit is set and disabled when the bit is clear, while on others, a set bit disables the interrupt. When the interrupt

Firstly, it disables all interrupts so that microcontroller cannot be able to execute any other interrupt service routine such as watchdog time, etc When you upload your code to a microcontroller, the binary image of code gets stored in flash memory. Because flash is a non-volatile memory. Th...
Handle the interrupt. In case of GPIOdirect external mode(i.e., ‘GPIO’ mode, by which I mean non-IOF functions, when the IOF_EN bit for that pin is set to 0), you must manually clear the pending interrupt before the handler returns. Otherwise, you will see a never-ending stream...
