3.1.6 Jumper B16 Selecting Address Block Width
Via the jumper B16, you are able to select if your VMOD-2 should occupy 256 Bytes of
address space, or when using certain enhanced piggybacks (which need/use additional
address decoding of A06...A11), in increased address steps of 8 KByte wide. The 256 byte
wide steps are numbered as AB (Address Blocks) from 01 to 32 in the table below.
Whenever the 8 KByte option is selected (i.e. jumper B16 is set) four consecutive AB#s are
occupied. These are also given to ensure that no address contention will occur when using
several VMOD-2's (and/or other boards) in your VMEbus system.
2b) Two piggybacks, both
unable to generate inter-
rupt vectors but can send
interrupt request are fitted
to the VMOD-2 and use
"Dumb" vectors (each with
different vector) Use a different
Jumper set
VMOD-2 Vec-
tor for each
piggyback B1 is to be
set to 1-2. Jumpers
B4...B11 are
set for appro-
priate byte cod-
ing. B11 is set
to 1-3.
3) One "intelligent" and one
"Dumb" piggyback are to
be fitted to the VMOD-2
and the user wants the
intelligent piggyback to
use it's on-board "Intelli-
gent" vector generation in
combination with "Dumb"
jumper coding. Use the
"Dumb" piggy-
back in upper
location, and
fit the "intelli-
gent" one in
lower location. B1 is to be
set to
bridge pins
1-3. Jumpers
B4...B11 are
set for desired
vector code to
be assigned
when piggy-
back "A"
makes an IRQ.
