EP93xx User’s Guide
User mode in Thumb state limits access to the low registers r0-r7. To access to the high
registers, the ARM Core must first revert to the ARM state. The high registers are:
• r0-r12: General purpose read/write 32-bit registers
• r13 (sp): Stack Pointer
• r14 (lr): Link Register
• r15 (pc): Program Counter
• cpsr: Current Program Status Register containing condition codes and operating modes
