Development Tools and Support
MC68160 EEST device. The LocalTalk connection is made through an RS-422 transceiver.
Applications not needing LocalTalk can use the RS-422 to implement other proprietary
LANs. The BDM output connector allows the QUADS board to control another device using
background debug mode. All these connections are made through the slave QUICC to pre-
vent master QUICC resources from being impacted.
If the user application includes a need for the RS-232 port, the system RS-232 port may be
used for the application if the host computer is connected to the QUADS board via the par-
allel port.
More detail of the QUADS system is shown in Figure B-3. Buffers are provided in this system
so that the system functions do not affect the fanout of the expansion connector. In a real
application, such buffers and the local bus arbiter are not necessarily required. The slave
QUICC provides the system integration functions (such as chip selects) that would normally
be provided by the QUICC's own SIM. Thus, the expansion connectors provide all the mas-
ter QUICC resources without using these resources and provide a non-degraded QUICC
electrical interface.
To assist with target board development, the QUADS board may be connected to the target
board through the edge connectors or through a PGA connector using a flexible PC board
supplied by a third party. (Adapters from PGA to PQFP are also available from third parties.)
Prototype boards may therefore make use of signals available from the QUADS develop-
ment board. Target board execution may be carried out with the QUICC executing from the
QUADS board memory, from target board memory, or a combination of both.
The QUADS board also contains connections for use by a logic analyzer, allowing all QUICC
pins to be examined. Connectors between the QUADS board and common logic analyzers
are available from third parties.
To connect the QUADS board to a host computer, a parallel interface cable and host inter-
face (ADI) board are supplied. Hosts include the IBM-PC and SUN-4 systems. Available
software executing on the host allows uploading and downloading of files and data between
the host and the QUADS board and allows control of the user interface module through a
window-based interface program resident on the IBM-PC or SUN-4. Source-level debugging
support through this interface and the serial interface is provided by third-party vendors.
B-8
The ADI boards mentioned here are the same ADI boards used
with the MC68302 ADS system. If the user already purchased
an ADI board for a MC68302 development project, that same
board may be used with the QUADS board as long as the ADI
board supports the IBM-PC, or SUN-4. The user only has to ob-
tain new host software (available on the BBS) to interface to the
QUADS board.
