MCF5407 Integrated ColdFire Microprocessor Product Brief
MOTOROLA
Programming Model, Addressing Modes, and Instruction Set
1.3.10 PLL Module
The MCF5407 PLL module is shown in Figure 3.
Figure 3. PLL Module
The PLL module’s three modes of operation (reset, normal, and reduced power) are described as follows.
Reset mode—When RSTI is asserted, the PLL enters reset mode. At reset, the PLL asserts RSTO
from the MCF5407. The core:bus frequency ratio along with other MCF5407 configuration
information are sampled during reset.
Normal mode—In normal mode, the input frequency programmed at reset is clock-multiplied to
provide the processor clock (PCLK).
Reduced-power mode—In reduced-power mode, the PCLK is disabled by executing a sequence
including programming a control bit in the system configuration register (SCR) and then executing
the STOP instruction. Register contents are retained in reduced-power mode, so the system can be
reenabled quickly when an unmasked interrupt or reset is detected.
1.4
Programming Model, Addressing Modes, and
Instruction Set
The ColdFire programming model is separated into two privilege modes—supervisor and user, which is
indicated by the S bit in the status register (SR). The processor identifies a logical address by accessing
either the supervisor or user address space, which differentiates between supervisor and user modes.
User mode—When the processor is in user mode (SR[S] = 0), only a subset of the registers can be
accessed and privileged instructions cannot be executed. Typically, most application processing
occurs in user mode. Entry into user mode is usually accomplished by executing a return from
exception instruction (RTE) (assuming the value of SR[S] saved on the stack is 0) or a MOVE, SR
instruction (assuming SR[S] is 0).
Supervisor mode—Supervisor mode protects system resources from uncontrolled access by users.
In supervisor mode, complete access to all registers and the entire ColdFire instruction set is
provided. Typically, system programmers use the supervisor programming model to implement
operating system functions and provide I/O control. The supervisor programming model provides
access to the same registers as the user model, plus additional registers for configuring on-chip
system resources, as described in Section 1.4.3, “Supervisor Registers.”
Exceptions (including interrupts) are handled in supervisor mode.
