When arbitration analysis is disabled, no emulation analyzer states are
created to mark the DMA transaction.
When arbitration analysis is enabled, the emulation analyzer will look at the
processor strobes to generate analyzer states showing the DMA address, data
and status information.

To select the normal or dedicated interrupt mode

1
Choose the Settings→Emulator Config→Hardware... (ALT, S, E, H)
command.
Select either the normal or dedicated option for the Interrupt Mode.
2
Choose the OK button to exit the Emulator Config dialog box.

This options tells the emulator which interrupt mode the 68302 is
programmed for -- it does not actually program the 68302 interrupt mode. If
the 68302 is not in the selected mode when a break is attempted, the break
will either fail or lead to unexpected interrupts.
When the interrupt mode is normal, the interrupts are encoded on /IPL0,
/IPL1, and /IPL2.
When dedicated, /IPL2 becomes /IRQ7, /IPL1 becomes /IRQ6, and /IPL0
becomes /IRQ1. In dedicated mode, edge or level sensitivity is selected via
the /IRQ7 mode checkbox.
