Figure 11.1 shows the types of interrupts.
Interrupts
•
•
The I flag and IPL can enable and disable these interrupts.
The interrupt priority order can be changed by using interrupt priority level settings.
These interrupts cannot be disabled regardless of the I flag and IPL settings.
Maskable interrupts
Non-maskable interrupt
Types of Interrupts
NOTES:
Interrupts
1. Peripheral function interrupts are generated by the on-chip peripheral functions in the MCU.
2. Do not use these interrupts. They are for use with development tool only.
