Introduction
modifying the S-bit of the SR. After these instructions execute, the instruction pipeline is
flushed and is refilled from the appropriate address space.
The MC68060 integrates the functions of the integer unit, FPU, and MMU. The registers
depicted in the programming model (see Figure 1-2) provide operand storage and control
for these three units. The registers are partitioned into two levels of privilege modes: user
and supervisor. The user programming model is the same as the user programming model
of the MC68040, which consists of 16 general-purpose 32-bit registers, two control regis-
ters, eight 80-bit floating-point data registers, a floating-point control register, a floating-point
status register, and a floating-point instruction address register.
Only system programmers can use the supervisor programming model to implement oper-
ating system functions, I/O control, and memory management subsystems. This supervisor/
