Memory-Mapped I/O Accessors
Create volatile 32-bit MMIO read/write helpers for bare-metal firmware.
Task
Implement mmio_write32(addr,value) and mmio_read32(addr) using volatile uint32_t pointer casts.
Examples
- Implement the required behavior and preserve it under the stated interface/control conditions.
Constraints
- Keep the implementation deterministic and consistent with the interface contract described in the task.
Concepts to review
C, MMIO, embedded
