The characteristics of NMI are as follows:
- They are also known as the non-maskable types.
- They are always give higher priorities over the INTR.
- The interrupt is edge triggered specifically Low to High transition.
- In order to function they must remain high for at least 2 cycles of CLK.
- These interrupts do not send out any form of acknowledgements.
The characteristics of INTR are:
- They are also known as the maskable types of interrupts.
