(1) Overview
PERIPHERAL RESOURCES
The interrupt controller receives and processes arbitration of interrupts.
This module is configured from the following elements.
• ICR register
• Interrupt priority determination circuit
• Interrupt level and interrupt number (vector) generator
• Hold request removal request generator
This module primarily provides the following functions.
• NMI request / interrupt request detection
• Order of priority determination (according to level and number)
• Notification (to CPU) of interrupt level of source according to determination
• Notification (to CPU) of interrupt number of source according to determination
• Instruction (to CPU) to recover from stop mode when an interrupt other than NMI/interrupt level “11111” is
• Generation of hold request removal requests to the bus master
