System Integration Block (SIB)
3.2.5 Interrupt Controller Programming Model
The user communicates with the interrupt controller using four registers. The global interrupt
mode register (GIMR) defines the interrupt controller's operational mode. The interrupt
pending register (IPR) indicates which INRQ interrupt sources require interrupt service. The
interrupt mask register (IMR) allows the user to prevent any of the INRQ interrupt sources
from generating an interrupt request. The interrupt in-service register (ISR) provides a ca-
pability for nesting INRQ interrupt requests.
3.2.5.1 Global Interrupt Mode Register (GIMR)
The user normally writes the GIMR soon after a total system reset. The GIMR is initially
$0000 and is reset only upon a total system reset. If bits V7–V5 of the GIMR are not written
to specify an interrupt vector prior to the first interrupt condition, the interrupt controller will
pass the vector $0F (the uninitialized interrupt vector), regardless of the interrupt source.
