Texas Instruments TM4C1294NCPDT User Manual

Register 14: Stack Pointer (SP)
The Stack Pointer (SP) is register R13. In Thread mode, the function of this register changes
depending on the ASP bit in the Control Register (CONTROL) register. When the ASP bit is clear,
this register is the Main Stack Pointer (MSP). When the ASP bit is set, this register is the Process
Stack Pointer (PSP). On reset, the ASP bit is clear, and the processor loads the MSP with the value
from address 0x0000.0000. The MSP can only be accessed in privileged mode; the PSP can be
accessed in either privileged or unprivileged mode.
