Interrupts
Notes:
1. Peripheral function interrupts are generated by the peripheral functions in the MCU.
2. Do not use these interrupts. This is provided exclusively for use by development tools.
3. A non-maskable or maskable interrupt can be selected by bits IRQ1SEL and IRQ2SEL in the CMPA register.
Figure 11.1 shows the Types of Interrupts.

(non-maskable interrupts)
These interrupts are enabled or disabled by the interrupt enable flag (I flag).
These interrupts are not enabled or disabled by the interrupt enable flag (I flag).
The interrupt priority can be changed based on the interrupt priority level.
