FUNCTIONAL DESCRIPTION
33
The ADI port connector is a 37 pin, male, D type connector. The connection between the M68360QUADS-
040 and the host computer is by a 37 line flat cable, supplied with the ADI board. FIGURE 4-2 below shows
the pin configuration of the connector.

ADI Port Signal Description
The ADI port on the QUADS-040 was slightly modified to generate either hard reset or soft reset. This
feature was added to comply with the QUICC’s reset mechanism. The host software written for the
QUADS-040 should be able to work properly with existing ADS boards, such as the M68302ADS.
In the list below, the directions ’I’, ’O’, and ’I/O’ are relative to the M68360QUADS-040 board. (I.E. ’I’ means
input to the M68360QUADS-040)
NOTE:
Since the ADI was originated for the DSP56001ADS, some of
its signals throughout the boards it was used with, were
designated with the prefix “ADS”. This convention is kept with
this design also.
