• Manufacturer Part Number: HD6417320
• Description: Renesas 32-Bit RISC Microcomputer SuperHTM RISC engine Family / SH7700 Series
• Manufacturer: RENESAS [Renesas Technology Corp]

The interrupt controller (INTC) determines the priority of interrupt sources and controls interrupt
requests to the CPU. The INTC registers set the priority of each interrupt, allowing the user to
process interrupt requests according to the user-set priority.
8.1
• 16 levels of interrupt priority can be set
• NMI noise canceller function
• IRQ interrupts can be set
• Interrupt request signal can be externally output (IRQOUT pin)
By setting the interrupt-priority registers, the priorities of on-chip peripheral modules, and IRQ
and PINT interrupts can be selected from 16 levels for individual request sources.
An NMI input-level bit indicates the NMI pin state. By reading this bit in the interrupt
exception service routine, the pin state can be checked, enabling it to be used as a noise
canceller.
Detection of low level, high level, rising edge, or falling edge
By notifying the external bus master that the external interrupt and on-chip peripheral module
interrupt requests have been generated, the bus mastership can be requested.
