The CPU16 programming model is similar to that of the M68HC11 CPU, and the CPU16 instruction set is
upwardly code-compatible with that of the M68HC11 CPU. However, the CPU16 also provides significant
additional capabilities. With dedicated multiply and accumulate registers and 18 instructions added specif-
ically for DSP support, M68HC16 family devices are general-purpose microcontrollers capable of perform-
ing DSP operations, not just DSP engines with a few additional embedded-control features. This is an
important distinction because most digital signal processors do not have bit manipulation capability, multiple
interrupt vectors, or a flexible software stack. Although M68HC16 devices do not perform multiply and ac-
cumulate operations as rapidly as some dedicated digital signal processors, they are ideally suited for ap-
plications such as motion control systems.
PID CONTROLLER BASICS
PID controllers offer some distinct advantages over other control topologies; but nothing is free —as in all
design processes, there must be trade-offs.

PID TRANSFER FUNCTION
The transfer function (as a function of s) is :
(EQ 1)
where:
C(s) is the output of the PID section
E(s) is the input to the PID section (usually servo error)
P is the multiplier for the servo error
I is the multiplier for the integral of the servo error
D is the multiplier for the derivative of the servo error
s is the Laplace complex frequency variable.
The previous equation shows that the PID controller has a pole at s = 0, and two zeros :
(EQ 2)
The two zeros are real-valued when 4DI
reveals that one of the zeros is used to brake the 20 dB/decade descent associated with the integrator, and
the other is used to provide a 20 dB/decade rise and positive phase lead required to stabilize the system.
