5.4
There are six types of interrupt sources: NMI, user break, H-UDI, IRQ, PINT, and on-chip
peripheral modules. Each interrupt has a priority level (0 to 16), with 0 the lowest and 16 the
highest. When set to level 0, that interrupt is masked at all times.
5.4.1
The NMI interrupt has a priority level of 16 and is accepted at all times. NMI interrupt requests
are edge-detected, and the NMI edge select bit (NMIE) in interrupt control register 0 (ICR0)
selects whether the rising edge or falling edge is detected.
Though the priority level of the NMI interrupt is 16, the NMI interrupt exception handling sets the
interrupt mask level bits (I3 to I0) in the status register (SR) to level 15.
5.4.2
A user break interrupt which occurs when a break condition set in the user break controller (UBC)
matches has a priority level of 15. The user break interrupt exception handling sets the I3 to I0 bits
in SR to level 15. For user break interrupts, see section 6, User Break Controller (UBC).
5.4.3
The high-performance user debugging interface (H-UDI) interrupt has a priority level of 15, and
occurs at serial input of an H-UDI interrupt instruction. H-UDI interrupt requests are edge-
detected and retained until they are accepted. The H-UDI interrupt exception handling sets the I3
to I0 bits in SR to level 15. For H-UDI interrupts, see section 23, High-Performance User
Debugging Interface (H-UDI).
