SCB->SHPR的寄存器组在资料上找不到这个知识点,我想看设置systick的优先级,求资料,求位置 卧听桃花雨 2020-07-24 07:48:47 寄存器与内存的区别 寄存器是中央处理器内的组成部份。它跟CPU有关。寄存器是有限存贮容量的高速存贮部件,它们可用来暂存指令、数据和位址。在中央处理器的控制部件中,包含的寄存器有指...

为0时,4字节对齐;为1时,8字节对齐。 8. SHPR 系统异常服务优先级寄存器,System Handler Priority Registers。 一共有三个这样的寄存器,标记为SHPR1,SHPR2,SHPR3,它们可以按字节访问。 SHPR1用于配置memory management fault(PRI_4), bus fault(PRI_5)和Usage fault(PRI_6); SHPR2用于配置SVCall(PRI_11);SH...

keil中加入RTOS编译后报错error: no member named 'SHPR' in 'SCB_Type'; did you mean 'SHP'? 在CMSIS中找一个rtx开头的文件右键点击Option for Component Class 'CMSIS' Variant项中选择Library 重新编译
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 ...
