Subject: KA630 CNF?
Date: Sunday, February 28, 1999 7:55 AM
Does anyone have any information on the KA630 CNF board? It is used
both with KA630s and KA650s to configure them for coprocessor mode.
All I have, is the KA630-AA CPU Module User's Guide.
Since I have never actually seen the board (which
plugs into the
KA630/650 directory), I'd specifically like to know what pins I
need to connect to establish the processor as the first, second and
third coprocessor...
If i read that right, there are 10 switches on this board. Switch 7 & 8 are
defined as:
7 8
off off Arbiter
on off auxiliary 1
off on auxiliary 2
on on auxiliary 3
Switch 7 is connected to pin 4 of the J2 connector (20 pin connector)
Switch 8 is connected to pin 5 of the J2 connector.
Don't have any of this boards, simply out of the manual.
Hope it helps,
emanuel
