在STM32的固件库中定义了三个结构体与这三个寄存器组相对应，这三个结构体与ARM⼿册中寄存器的对应关系如下：
⼀、NVIC寄存器组
STM32的固件库中有如下定义：
typedef struct
{
vu32 ISER[2];
u32 RESERVED0[30];
vu32 ICER[2];
u32 RSERVED1[30];
vu32 ISPR[2];
u32 RESERVED2[30];
vu32 ICPR[2];
u32 RESERVED3[30];
vu32 IABR[2];
u32 RESERVED4[62];
vu32 IPR[11];
} NVIC_TypeDef;
它们对应ARM⼿册中的名称为
ISER = Interrupt Set-Enable Registers
ICER = Interrupt Clear-Enable Registers
ISPR = Interrupt Set-Pending Register
ICPR = Interrupt Clear-Pending Register
IABR = Active Bit Register
IPR = Interrupt Priority Registers
每个寄存器有240位，以Interrupt Set-Enable Registers说明，ISER[0]对应中断源0~31，ISER[1]对应中断源32~63，STM32只有60个中断源，所以没有ISER[2:7]。

参考STM32技术参考⼿册中的中断向量表，中断源的位置为：
位置0 - WWDG = Window Watchdog interrupt
位置1 - PVD = PVD through EXTI Line detection interrupt
位置2 - TAMPER = Tamper interrupt
......
位置58 - DMA2_Channel3 = DMA2 Channel3 global interrupt
位置59 - DMA2_Channel4_5 = DMA2 Channel4 and DMA2 Channel5 global interrupts
⼆、系统控制寄存器组
STM32的固件库中有如下定义：
typedef struct
{
vuc32 CPUID;
vu32 ICSR;
vu32 VTOR;
vu32 AIRCR;
vu32 SCR;
vu32 CCR;
vu32 SHPR[3];
vu32 SHCSR;
vu32 CFSR;
vu32 HFSR;
vu32 DFSR;
vu32 MMFAR;
vu32 BFAR;
vu32 AFSR;
} SCB_TypeDef; /* System Control Block Structure */它们对应ARM⼿册中的名称为
CPUID = CPUID Base Register
ICSR = Interrupt Control State Register
VTOR = Vector Table Offset Register
AIRCR = Application Interrupt/Reset Control Register SCR = System Control Register
CCR = Configuration Control Register
SHPR = System Handlers Priority Register SHCSR = System Handler Control and State Register CFSR = Configurable Fault Status Registers
HFSR = Hard Fault Status Register
DFSR = Debug Fault Status Register
MMFAR = Mem Manage Address Register
BFAR = Bus Fault Address Register
AFSR = Auxiliary Fault Status Register
三、系统时钟寄存器组
STM32的固件库中有如下定义：
typedef struct
{
vu32 CTRL;
vu32 LOAD;
vu32 VAL;
vuc32 CALIB;
} SysTick_TypeDef;
它们对应ARM⼿册中的名称为
CTRL = SysTick Control and Status Register LOAD = SysTick Reload Value Register VAL = SysTick Current Value Register CALIB = SysTick Calibration Value Register。
