5.2 ARCHITECTURE SUMMARY
The CPU32 is upward source- and object-code compatible with the MC68000 and
MC68010. It is downward source- and object-code compatible with the MC68020. Within
the M68000 family, architectural differences are limited to the supervisory operating state.
User state programs can be executed unchanged on upward-compatible devices.
The major CPU32 features are as follows:
5.2.1 Programming Model
The CPU32 programming model consists of two groups of registers that correspond to the
user and supervisor privilege levels. User programs can only use the registers of the user
model. The supervisor programming model, which supplements the user programming
model, is used by CPU32 system programmers who wish to protect sensitive operating
system functions. The supervisor model is identical to that of MC68010 and later
processors.
The CPU32 has eight 32-bit data registers, seven 32-bit address registers, a 32-bit PC,
separate 32-bit SSP and USP, a 16-bit SR, two alternate function code registers, and a
32-bit VBR (see Figures 5-3 and 5-4).
