10.3.4
This 7-bit register is updated each machine cycle and represents the current interrupt requests for each
interrupt level, where bit 7 corresponds to level 7, bit 6 to level 6, etc. This register output is combined
with similar outputs from INTC1 and eventually encoded into the 3-bit priority interrupt level driven to
the processor core.
10.3.5
Each time an IACK is performed, the interrupt controller responds with the vector number of the highest
priority source within the level being acknowledged. In addition to providing the vector number directly
for the byte-sized IACK read, this 8-bit register is also loaded with information about the interrupt level
and priority being acknowledged. This register provides the association between the acknowledged
“physical” interrupt request number and the programmed interrupt level/priority. The contents of this
read-only register are described in
