Interrupt Controller Registers
The SIM provides the following registers for managing interrupts:
9.2 Interrupt Controller Registers
The interrupt controller register portion of the SIM memory map is shown in Table 9-2.
Each internal interrupt source has its own interrupt control register (ICR0–ICR9), shown in
Table 9-2 and described in Section 9.2.1, “Interrupt Control Registers (ICR0–ICR9).”

• Each potential interrupt source is assigned one of the 10 interrupt control registers
• The interrupt mask register (IMR) provides bits for masking individual interrupt
• The interrupt pending register (IPR) provides bits for indicating when an interrupt
• The autovector register (AVEC) controls whether the SIM supplies an autovector or
• The interrupt port assignment register (IRQPAR) provides the level assignment of
