ACR8010 MOTHERBOARD PLUG AND PLAY CAPABILITY
Interrupt Select
The ACR8010 can be instructed to interrupt a PC host through the parallel bus by issuing
a SET 112 command in immediate mode or from within a program. Interrupt driven
software at the host level is an advanced topic and should only be attempted by someone
with a thorough knowledge of interrupt driven code.
In order for the PC to see the interrupt, the proper interrupt selection from the following
table must be made. The interrupt is automatically configured in Windows 95 using the
ACR8010’s Plug and Play interface. When using DOS or Windows NT, the interrupt is
selected using the supplied ACROPNP utilities.
NOTE: It is important to read the README file located on the Acroloop CD
before attempting any PC installation of the ACR8010 board.
