• Manufacturer Part Number: HD6417660
• Description: Renesas 32-Bit RISC Microcomputer
• Manufacturer: RENESAS [Renesas Technology Corp]

IRQ interrupt and on-chip peripheral module interrupt priorities can be set properly between 0 and
15 for each module by setting interrupt priority registers A to C and F to H (IPRA to IPRC and
IPRF to IPRH). A reset assigns priority level 0 to IRQ and on-chip peripheral module interrupts.
If the same priority level is assigned to two or more interrupt sources and interrupts from those
sources occur simultaneously, their priority order is the default priority order indicated at the right
in table 8.4.
