Interfacing to a Motorola
Microprocessor-Based System
Interfacing to a Motorola 68000 family device is relatively simple. Bus timing and interface signal
definitions closely match those of the 68000 microprocessor, which allows a direct connection.
With later versions (68020, 68030), some additional logic is required to generate the DSACK0*
and DSACK1* functions that replace the DTACK* on earlier devices.
Figure 14
shows a
generalized interface to a 68020 device.
