Vic Interrupt Listing; Table 10-1. Interrupt Assignments - Sharp Blue Treak LH75400 User Manual

Vectored Interrupt Controller
Any of the 32 lines can be assigned to any of the 16 interrupt vectors. Any line not explicitly
assigned to an interrupt vector is processed as a default-vectored interrupt. At reset, all
32 lines are set to be default-vectored interrupts.
Each interrupt line can be explicitly identified as either an IRQ interrupt type (default)
or an FIQ interrupt type. Vectored-interrupt servicing is only available for IRQ interrupts.
Although more than one interrupt source can be designated as FIQ, only one source nor-
mally is designated to take advantage of the low latency of FIQ exception handling for a
specific need.

10.1.2 VIC Interrupt Listing

Table 10-1 lists the 32 interrupt source lines for the VIC. For a detailed description of each
interrupt, see the description of the peripheral that generates that interrupt
position 31 is version-specific for each device.
