2.3.2 Interrupt level (JP1)
The jumper JP1 selects the card's interrupt level (2, 4, 5, 7, 10, 11, 12, 15) as shown
below:
Card interrupt (default = 7)
Do not select a level that is being used by another device unless you have performed
special programming to share several devices on one interrupt.
To use the interrupt you must install an interrupt service routine and program the
PCL-833's on-board the 8259 interrupt controller.
Nine different conditions can enable the PCL-833's interrupt, but only one at a time.
Bit 3 of register BASE+9 switches interrupt source 7 between the card's TIMER and
Dl1. See Chapter 3 for details.
You should treat all the interrupt sources as positive-edge triggered when you pro-
gram the 8259.
