The Cortex-M3 processor features general-purpose registers R0-R15 along with several special function registers. Registers R0-R12 are 32-bit general-purpose registers used for data operations. However, most 16-bit Thumb instructions can only use R0-R7 (the low register group), while 32-bit Thumb-2 instructions can access all general-purpose registers. The special function registers have predefined functions and must be … Read more
