ARM Compiler toolchain Assembler Reference MSR. The memory capacity of the ARM processor is 64 Mbytes, or 16 Mwords. The PC is always a multiple of four because of the two appended zeros, and so it follows that instructions must be aligned to four byte boundaries. Special bits in some instructions allow the PC and PSR to …, ARM Cortex-M Bare-Metal Embedded-C Programming the learner can understand how the C statements translate to machine instructions and how fast the ARM PSR.
