WebAVR Interrupt Vectors. Below are tables of the interrupts available on the AVR microcontrollers used in class. The vector name is the identifier that should be used at the start of the the interrupt service routine (ISR). For example, the ISR for the ATmega328P Pin Change Interrupt Request 0 would look like this. Note: The names of the vectors ... WebIn the code below, with the first line in the void setup, we enable PCIE2 because D5 corresponds to that group. With the second line we indicate taht PCINT21 will trigger interrupt because D5 is represented by taht group. Everything is set bwe we need to define the ISR vector. To pin D5 which is from port D, the ISR that corresponds is vector 2.

WebSep 23, 2024 · What is Interrupt Vector Table ( IVT) ? It is a table of Interrupt Vectors (pointers to routines that handle interrupts). The vector table contains the reset value of the stack pointer, and the start addresses, also called exception vectors, for all exception handlers. Each interrupt request number is reserved for a specific purpose. Web5. Interrupt Vector Table The first entry in the table (lowest address) contains the initial MSP. All other addresses contain the vectors (addresses) to the start of exception handlers (ISRs), each address is 4-Byte wide. The table has up to 496 external interrupts which is implementation-dependent on each specific target.
