7.9 Rabbit Interrupt Structure
An interrupt causes a call to be executed, pushing the PC on the stack and starting to exe-
cute code at the interrupt vector address. The interrupt vector addresses have a fixed lower
byte value for all interrupts. The upper byte is adjustable by setting the registers EIR and
IIR for external and internal interrupts respectively. There are only two external interrupts
generated by transitions on certain pins in parallel port E.
The interrupt vectors are shown in Table 7-11.
