In C programming, you can use the intrinsic functions provided in Cortex Microcontroller Software Interface Standard (CMSIS) compliant device driver libraries or provided in the compiler to set and clear PRIMASK: void __enable_irq(); // Clear PRIMASK void __disable_irq(); // Set PRIMASK void...
2014,PIC Microcontroller Projects in C (Second Edition) DoganIbrahim Chapter Real Time 6.4.2Interrupt Service Routines The code executed as a result of an interrupt being serviced is called an “interrupt service routine” (ISR). This routine is similar to a normal subroutine (or C function),...

So, for external interrupt line 0, we simply need to create a void function duplicating the name used in the vector table: void EXTI0_IRQHandler (void); This now becomes ourinterrupt service routine. In addition, we must configure themicrocontroller peripheraland NVIC to enable the interrupt ch...
Sign in to download full-size image Figure 6.4. The 16F84A interrupt response sequence of events In the PIC 16 Series, the ISR must start at the interrupt vector, program memory location 0004 (Figure 2.4). Therefore, when an interrupt occurs, this value is loaded into the Program Counter ...
In C language, an interrupt handler could be like void UART1_Handler(void) { ... // processing task for the peripheral return; } For users of the CMSIS compliant device driver library, the interrupt handler name should match the interrupt handler name defined by the Microcontroller Unit (MCU...

Mitsubishi M37267M8 8-bit TV Microcontroller Interrupt table.[5] Several different priority schemes are implemented in the various architectures. These schemes commonly fall under one of three models: the equal single level, where the latest interrupt to be triggered gets the CPU; the static multi...
