Hardware Configurations
The simplicity of the CPU interface to the CD1283 allows the device to be designed into systems
that employ popular microprocessors such as the Intel 80x86 family (8086, 80286, 80386, and so
on) and the Motorola
family (68000, 68010, 68020, and so on).
An example of CD1283 configuration for a laser-printer application is shown in
Figure 12
. This
example provides a parallel interface, as well as general-purpose I/O for static control/status.
