This manual documents the Microcontroller profile of version 7 of the ARM Architecture, the ARMv7-M architecture profile.
ARMv7-M supports debug stepping in both halting debug and monitor debug, see: Halting debug stepping Debug monitor stepping. Halting debug stepping A debugger controls stepping in halting debug by writing to the DHCSR.C_STEP and DHCSR.C_HALT bits, see Debug Halting Control and Status Register,...

ARMv7一共有37个寄存器,如下图所示: user模式下一共有r0~r15加上cpsr,17个寄存器,FIQ模式下灰色部分是自己的,即r8 ~ r14和spsr寄存器是自己的,其他的是usermode的,以此类推; 1.通用寄存器 r0 ~ r12是通用寄存器,就是计算的时候会用到,没有特殊的含义 2.SP/LR/PC特殊寄存器 SP是堆栈指针寄存器,用于保护现...

ARMv7架构是一个32位处理器架构。它是一种load/store架构,意味着数据处理指令操作通用寄存器中的值。只有加载(load)和存储(store)指令访问存储器。通用存储器也是32位的。本书中,字(word)代表32位,双字(doubleword)代表64位,半字(halfword)代表16位宽。
