Interrupt Controller Registers
Table 7-6 describes PIWR fields.
7.2.6 Programmable Interrupt Vector Register (PIVR)
The programmable interrupt vector register (PIVR), Figure 7-9, specifies the vector
numbers the interrupt controller returns in response to interrupt acknowledge cycles for the
various peripherals and discrete interrupt sources.
Pending interrupts are presented to the processor core in order of priority from highest to
lowest. The core responds to an interrupt request by initiating an interrupt acknowledge
cycle to receive a vector number, which allows the core to locate the interrupt’s service
routine. The interrupt controller is able to identify the source of the highest priority
interrupt that is being acknowledged and provide the interrupt vector to the core. The three
most significant bits of the interrupt vector are programmed by the user in the PIVR. The
lower five bits are provided by the interrupt controller, depending on the source, as shown
in Table 7-7.
