FUNCTIONAL DESCRIPTIONS
2.1
CPU Interface
The CPU interface is 8 data bits wide with 3 address lines and control signals to execute data bus read and
write transactions. The M680 data interface supports the Intel and Motorola compatible types of CPUs. No
clock (oscillator nor external clock) is required for a data bus transaction. Each bus cycle is asynchronous
using CS#, IOR# and IOW# or R/W# inputs. A typical data bus interconnection for Intel and Motorola mode is
shown in Figure 4.
