Don’t worry too much about the work done by the handler; the form of the C interrupt service routine is what you need to understand at this point. Note that all interrupt functions must be of typevoidand have no arguments. Since the address of this function will be placed in the proce...
A:That button is for our call screening function. It allows you to identify the caller before you answer the call. 那个按钮是来电显示功能。它可以让您在接电话之前先知道是谁来电。 interrupt是什么意思 B:What else can you tell me about this phone?

language code. However, within those operations, the processor is expected to call and return from a C function. In this section, we describe the assembly language task of handling registers; in the next, we show some of the acrobatics required in the C function that is subsequently invoked....
The compiler will place RETFIE automatically if it sees a C "return" statement at the top level of the ISR, which is the only place it can legally appear. You mean they're many function levels down. May be setjmp()/longjmp() would help - I don't know if they're implemented in XC3...
The ISR must be coded to respond with a SYSINTR_ . . . response as in the OAL ISR. The LoadIntChainHandler function loads the ISR dynamic-link library (DLL) into the kernel's address space. This implies that the code cannot call any non-kernel functions including any C-language runtim...
play in managing irqs? bios handles hardware initialization, including managing irq assignments during the boot process. it sets up the interrupt controllers and configures irq priorities, ensuring a stable hardware environment for the operating system to function correctly. how can i optimize irq ...
