Section 9 Interrupt Controller (INTC)
Rev. 1.00 Oct. 01, 2007 Page 297 of 1956
REJ09B0256-0100
The priority order of the on-chip modules is specified as desired by setting priority levels from 31
to 0 in INT2PRI0 to INT2PRI14. The priority order of the on-chip modules is set to 0 by a reset.
When the priorities for multiple interrupt sources are set to the same level and such interrupts are
generated simultaneously, they are handled according to the default priority order shown in table
9.7.
Updating of INTPRI and INT2PRI0 to INT2PRI14 should only be carried out when the BL bit in
SR is set to 1. To prevent erroneous interrupt acceptance, first read one of the interrupt priority
level setting registers, then clear the BL bit to 0. This will secure the necessary timing internally.
