1. ARM Cortex-M0 Registers Detailed Overview with Diagrams

2. Introduction The ARM Cortex-M0 is a 32-bit microcontroller designed for low-power applications. It has a simple and efficient register set that plays a crucial role in the operation of the processor.

3. General-Purpose Registers (R0-R15) The ARM Cortex-M0 processor includes 16 general-purpose registers (R0 to R15): • R0-R12: 32-bit registers used for data operations, arithmetic, and logical operations. • R13 (Stack Pointer - SP): Points to the top of the stack. Two stack pointers are available: MSP and PSP. • R14 (Link Register - LR): Holds the return address for functions. • R15 (Program Counter - PC): Contains the address of the next instruction to be executed.

4. Special Registers The Cortex-M0 also includes several special registers: • Program Status Register (PSR): Combines APSR, IPSR, and EPSR. • Interrupt Mask Registers: PRIMASK, FAULTMASK, and BASEPRI. • Control Register (CONTROL): Configures the processor's operating mode and stack pointer.

5. Floating Point Unit (FPU) Registers • The Cortex-M0 typically does not include an FPU. • In processors with an FPU, additional floating-point registers (S0-S31) are available. • These registers are used for high-precision floating-point calculations.
