13.2.1.4 Interrupt Request Level Register (IRLRn)
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
from both interrupt controllers (INTC0 & INTC1) are combined encoded into the 3-bit priority
interrupt level driven to the processor core.
13.2.1.5 Interrupt Acknowledge Level and Priority Register (IACKLPRn)
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
