6.4.2
On-chip peripheral module interrupts are interrupts generated by the following on-chip peripheral
modules.
As a different interrupt vector is assigned to each interrupt source, the exception service routine
does not have to decide which interrupt has occurred. Priority levels between 0 and 15 can be
assigned to individual on-chip peripheral modules by setting interrupt priority registers A, D to K
(IPRA, IPRD to IPRK). On-chip peripheral module interrupt exception processing sets the
interrupt mask level bits (I3 to I0) in the status register (SR) to the priority level value of the on-
chip peripheral module interrupt that was accepted.
