S:36/8 Status DII Lost
This bit is set anytime a DII interrupt occurs while the DII
Pending bit (S:2/11) is also set. When set, you are notified
that a DII interrupt has been lost. For example, the interrupt
is lost because a previous interrupt was already pending
and waiting execution. Examine this bit in your user
program and take appropriate action if your application
cannot tolerate this condition. Then clear this bit with your
user program to prepare for the next possible occurrence of
this error.

S:36/9 Status STI Lost
This bit is set anytime an STI interrupt occurs while the STI
Pending bit (S:2/0) is also set. When set, you are notified
that a STI interrupt has been lost. For example, the interrupt
is lost because a previous interrupt was already pending
and waiting execution. Examine this bit in your user program
and take appropriate action if your application cannot
tolerate this condition. Then clear this bit with your user
program to prepare for the next possible occurrence of this
error.
