MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -Maskable interrupts are those interrupts that can be temporarily ignored by the system. The CPU can decide whether to handle them or not based on the current system state. Here are some key points to know about maskable interrupts:-These interrupts can be enabled or disabled by software.

Detailed explanation-2: -An interrupt whose interrupt service can be stopped from being serviced temporarily is called Maskable Interrupt.

Detailed explanation-3: -A maskable interrupt is a hardware interrupt that may be ignored by setting a bit in an interrupt mask register’s (IMR) bit-mask. In contrast, nNon-maskable interrupt is a hardware interrupt that lacks an associated bit-mask, so that it can never be ignored.

Detailed explanation-4: -What is Maskable Interrupt? A hardware interrupt that could be ignored by setting a bit in the interrupt mask register’s (IMR) bit-mask is referred to as a maskable interrupt. The microprocessor may suppress or ignore maskable interrupts, and the interruptions are either edge-triggered, level-triggered, or both.

Detailed explanation-5: -A commendable example of Non-Maskable Interrupt is the Trap of 8085.
