要使用STM32，需要各種文檔，其中有（以STM32F103RBT6為例）：

非官方的：

下面，我們看看關(guān)于NVIC寄存器的描述，都在哪些手冊里面有提到

在使用STM32F10x standard peripheral library寫有關(guān)于stm32中斷的程序的時候，需要開啟某個特定中斷的控制位，除了對應(yīng)外設(shè)的寄存器之外，還需要設(shè)置NVIC的相關(guān)寄存器的對應(yīng)位。例如：

/******STM32specificInterruptNumbers*********************************************************/WWDG_IRQn=0,/*!

而NVIC_Init()這個函數(shù)：

/***@briefInitializestheNVICperipheralaccordingtothespecified*parametersintheNVIC_InitStruct.*@paramNVIC_InitStruct:pointertoaNVIC_InitTypeDefstructurethatcontains*theconfigurationinformationforthespecifiedNVICperipheral.*@retvalNone*/voidNVIC_Init(NVIC_InitTypeDef*NVIC_InitStruct){uint32_ttmppriority=0x00,tmppre=0x00,tmpsub=0x0F;/*Checktheparameters*/assert_param(IS_FUNCTIONAL_STATE(NVIC_InitStruct->NVIC_IRQChannelCmd));assert_param(IS_NVIC_PREEMPTION_PRIORITY(NVIC_InitStruct->NVIC_IRQChannelPreemptionPriority));assert_param(IS_NVIC_SUB_PRIORITY(NVIC_InitStruct->NVIC_IRQChannelSubPriority));if(NVIC_InitStruct->NVIC_IRQChannelCmd!=DISABLE){/*ComputetheCorrespondingIRQPriority--------------------------------*/tmppriority=(0x700-((SCB->AIRCR)&(uint32_t)0x700))>>0x08;tmppre=(0x4-tmppriority);tmpsub=tmpsub>>tmppriority;tmppriority=(uint32_t)NVIC_InitStruct->NVIC_IRQChannelPreemptionPriority<NVIC_IRQChannelSubPriority&tmpsub;tmppriority=tmppriority<<0x04;NVIC->IP[NVIC_InitStruct->NVIC_IRQChannel]=tmppriority;/*EnabletheSelectedIRQChannels--------------------------------------*/NVIC->ISER[NVIC_InitStruct->NVIC_IRQChannel>>0x05]=(uint32_t)0x01<<(NVIC_InitStruct->NVIC_IRQChannel&(uint8_t)0x1F);}else{/*DisabletheSelectedIRQChannels-------------------------------------*/NVIC->ICER[NVIC_InitStruct->NVIC_IRQChannel>>0x05]=(uint32_t)0x01<<(NVIC_InitStruct->NVIC_IRQChannel&(uint8_t)0x1F);}}
