Maskable Interrupts − The interrupts which can be masked i.e. disabled are called maskable interrupts. The microprocessor can ignore or delay a maskable interrupt if it is performing some critical task and don't want to be interrupted. 8085 microprocessor has four maskable interrupts i.e. INTR, RST 7.5, RST 6.5, RST 5.5.
Non-maskable interrupt − The interrupts which cannot be disabled or masked are called non-maskable interrupts. TRAP is a non-maskable interrupt in 8085 microprocessor.
