Int Fixed = Vector is pre-fixed on-board the piggyback
Int Progr = programmable vector on piggyback
2.2.4 Interrupt Vector Setting
As described before, the user can set his VMOD-2's Interrupt Vectors as appropriate to his
VMOD-2/Piggyback configurations needs. The selection of these vectors is subject to the
binary code of bits D0...D7 as derived by the setting of jumpers B11 to B4 respectively. B11 is
a three-pin type and can provide an identical or different vector for the two piggybacks. Three
examples are given below where jumper B1 must be set to 1-2 to use these vectors.
* = If jumper B11 is set for 1-3, D0 will return a "0" for piggyback "A" and a "1" for
piggyback "B".
When jumper B11 is set to 1-2 the vector of both piggyback locations "A" and "B"
will be the same (so D0 = 0).
When jumper B11 is open the vector of both piggyback locations "A" and "B" will
also be the same (but D0 = 1).
