Figure 4-1: Typical Implementation of MC68328 to SED1374 Interface - MC68K #1
The interface between the MC68328 and the SED1374 can be implemented using either the
MC68K #1 or Generic #1 host bus interface of the SED1374.
The MC68328 multiplexes dual functions on some of its bus control pins (specifically
UDS, LDS, and DTACK). In implementations where all of these pins are available for use
as bus control pins, then the SED1374 interface is a straightforward implementation of the
“MC68K #1” host bus interface. For further information on this host bus interface, refer to
the SED1374 Hardware Functional Specification, document number
X26A-A-001-xx.
The following diagram shows a typical implementation of the MC68328 to SED1374 using
the MC68K #1 host bus interface.
