Jumpers J3-J10 are all two position jumpers, with the two positions labeled " A "
and "B" . Figure 2-5 shows an enlarged view of jumper Jl0 and how the two positions
are labeled. The remaining 7 jumpers are all identical to jumper Jl0.
Figure 2-5. Interrupt Input Edge Selection Jumper Jl0
If a jumper is set in position
"A"
, then that interrupt input line will latch the interrupt
input on the low to high transition of the
signal.
Likewise, if a jumper is set to posi-
tion " B " then that interrupt input line will latch the interrupt input on the high to
low transition of the signal. Table 2-7 reiterates this concept.
