R-INT
The PR pin is for a programmed interrupt from the SPARCstation to the
VMEbus processor. Pins 1 and 5 in the left column and the two pins in the
right column are not used.
The PR Interrupt may be asserted as VMEbus IRQ1 or VMEbus IRQ2 through
the
R-INT
jumper block. IRQ1 and IRQ2 may be jumpered or wire-wrapped
to the PR pin to allow the interrupt source to cause an IRQ1 or IRQ2 interrupt
on the VMEbus backplane.
For example, to have VMEbus IRQ2 asserted when a SBus processor invokes
a PR Interrupt
,
place a jumper between the VMEbus IRQ2 and PR pins.
The five interrupt sources (one of the five is not used) in this jumper block are
open-collector and more than one may be wire-OR'ed to the VMEbus IRQ1
and IRQ2 pins.
The VMEbus level chosen for the PR Interrupt to drive cannot be
configured for SBus handling; if it is, the PR Interrupt will interrupt the
SPARCstation.
