In this tutorial, we will talk about the interrupt vector table. Firstly, we will define the interrupt vector table (IVT). Secondly, we will see the role of IVT for interrupts and exceptions processing in microcontrollers or microprocessors. After that, we will see the interrupt vector table o...
What does interrupt vector mean to you?A letter to the editor is presented in response to the article "Coming to Terms with Interrupt Vectors and Tables," by Dan Saks in the November 2006 issue.ZammattioStefanoOkeyIanKloecknerRuedigerGustafson...
If a trigger flag is set, but the interrupts are disabled (I=1),the interrupt level is not high enough, or the flag is disarmed, the request is not dismissed. Rather the request is held pending, postponed until a later time, when the system deems it convenient to handle the requests. ...
Making small talk is a way to start a conversation with a stranger when meeting for the first time. It isn't easy to make small talk with people. You don't know. Sitting by yourself and saying nothing at a party is rude. Making small talk is necessary to build business relations. Mak...

Like a hardware interrupt, it calls only a specific interrupt vector and saves the accumulators and registers. A software interrupt can also make use of some of the hardware interrupt routines. Similar in functionality to a subroutine call, a software interrupt is used for different purposes in ...
services of all other devices, stopping the instruction that's currently processing and saving its configuration in a register. Then it will load the interrupt'sprogram counterfrom a location given by the interrupt vector table. Once ISR execution is complete, it will reinitialize all interrupt ...

But the warning is not output, even if interrupt wasn't initialized using Pragma vector. (I used CCSv6.1 : Compiler version TI v4.4.6) Why isn't the warning output ? Isn't this define("type = VECT_INIT") necessary ? Best regards, ...
