Maskable interrupt :
An interrupt which can be enabled (disabled) by the interrupt enable flag
(I flag) or whose interrupt priority can be changed by priority level.
Non-maskable interrupt : An interrupt which cannot be enabled (disabled) by the interrupt enable flag
(I flag) or whose interrupt priority cannot be changed by priority level.
