IVR - Interrupt Vector Register
Bits 7:0

This is the unmodified form of the interrupt vector.

The table above indicates how the IVR may be modified by the
interrupting source. The modification of the IVR as it is presented to
the data bus during an IACK cycle is controlled by the setting of the
bits (2:1) in the GCCR (Global Chip Configuration Register)
