FUNCTIONAL DESCRIPTIONS

2.1

Host Data Bus Interface

The host interface is 8 data bits wide with 3 address lines and control signals to execute bus read and write

transactions. The 650A supports 3 type of host interfaces: Intel, Motorola and PC mode. The Intel and

Motorola interfaces provide support for their respective microcontroller or processor. This facilitates the

hardware design and interconnections. The Intel bus interface is selected by connecting IM# to logic 0 and

SEL to logic 1. The Intel bus interconnections are shown in Figure 3. The Motorola bus is selected with the IM#

input connected to logic 1 and SEL input ties to logic 1. The Motorola bus interconnections are shown in

Figure 4. The special PC mode is selected when IM# and SEL are connected to logic 0. The PC mode

interconnections are shown in Figure 5.
