Only system control software is intended to use the supervisor programming model 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:
Freescale Semiconductor
• One 32-bit status register (MACSR) including four indicator bits signaling product or
• 16-bit status register (SR)
• 32-bit supervisor stack pointer (SSP)
• 32-bit vector base register (VBR)
• 32-bit cache control register (CACR)
• Two 32-bit access control registers (ACR0, ACR1)
• Two 32-bit base address registers (RAMBAR)
accumulation overflow (one for each accumulator: PAV0–PAV3)
