MCF52211 ColdFire® Integrated Microcontroller Reference Manual, Rev. 2
Freescale Semiconductor 3-3
The supervisor-programming model is intended to be used only by system control software to implement
restricted operating system functions, I/O control, and memory management. All accesses that affect the
control features of ColdFire processors are in the supervisor programming model, which consists of
registers available in user mode as well as the following control registers:
• 16-bit status register (SR)
• 32-bit supervisor stack pointer (SSP)
• 32-bit vector base register (VBR)
