6. Interrupt Controller (INTC)
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 in interrupt priority registers A to J (IPRA to
IPRJ). 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.
6.4.3
A user break interrupt has a priority of level 15, and occurs when the break condition set in the
user break controller (UBC) is satisfied. User break interrupt requests are detected by edge and are
held until accepted. User break interrupt exception processing sets the interrupt mask level bits (I3
to I0) in the status register (SR) to level 15. For more details on the user break interrupt, see
section 7, User Break Controller (UBC).
