4.3 S1D13705 Host Bus Interface
4.3.1 Host Bus Pin Connection
Interfacing to the Motorola ‘Dragonball’ Family of Microprocessors
Issue Date: 01/02/13
This section is a summary of the host bus interface modes available on the S1D13705 that
may be used to interface to the MC68VZ328.
The S1D13705 implements a 16-bit interface to the host microprocessor which may operate
in one of several modes compatible with most of the popular embedded microprocessor
families. The two interface modes that may be used for the MC68VZ328 are:
• Motorola MC68K #1 (using Upper Data Strobe / Lower Data Strobe).
• Generic #1 (Chip Select, plus individual Read Enable/Write Enable for each byte).
The following table shows the functions of each host bus interface signal.
For details on configuration, refer to the S1D13705 Hardware Functional Specification,
document number X27A-A-001-xx.
