9.4.2
The secondary controller serves 64 interrupt sources with programmable interrupt levels. All 64 interrupts
are auto-vectored. Interrupt pending registers and interrupt mask registers are decentralized, and available
in the modules that own the interrupts.

Reserved.
Each Interrupt Pending bit corresponds to an interrupt source defined by the Interrupt Control Register. At every
clock this register samples the signal generated by the interrupting source. The corresponding bit in this register
reflects the state of the interrupt signal even if the corresponding mask bit were set. The IPR is a read-only longword
register.
0 The corresponding interrupt source does not have an interrupt pending
1 The corresponding interrupt source has an interrupt pending
Reserved, should be cleared.
