Overview of 8085 μP Interrupts
The 8085 microprocessor (μP) is equipped with a variety of interrupts that enhance its capability to manage multiple tasks efficiently. Interrupts are signals that temporarily halt the processor's current operations, allowing it to address urgent tasks.
Total Number of Interrupts
The 8085 μP has a total of 5 interrupts:
Characteristics of 8085 Interrupts
Conclusion
Understanding the interrupt structure of the 8085 μP is crucial for designing effective systems that require real-time processing and quick responses to external signals. The correct answer to the number of interrupts in 8085 μP is indeed 5 (option B).
The 8085 microprocessor (μP) is equipped with a variety of interrupts that enhance its capability to manage multiple tasks efficiently. Interrupts are signals that temporarily halt the processor's current operations, allowing it to address urgent tasks.
Total Number of Interrupts
The 8085 μP has a total of 5 interrupts:
- TRAP: This is a non-maskable interrupt with the highest priority, used for critical tasks.
- RST7.5: A maskable interrupt with a higher priority that can be enabled or disabled.
- RST6.5: Another maskable interrupt that is lower in priority than RST7.5.
- RST5.5: This is a maskable interrupt with priority lower than RST6.5.
- INTR: The simplest form of interrupt that can be triggered by external devices; it has the lowest priority.
Characteristics of 8085 Interrupts
- Maskable vs. Non-Maskable: TRAP is non-maskable, whereas the other interrupts (RST 5.5, 6.5, 7.5, and INTR) are maskable, meaning they can be ignored by the CPU if required.
- Prioritization: The interrupts have different priorities, with TRAP being the highest and INTR being the lowest.
- Usage: These interrupts allow the processor to respond to critical events, improving system efficiency and responsiveness.
Conclusion
Understanding the interrupt structure of the 8085 μP is crucial for designing effective systems that require real-time processing and quick responses to external signals. The correct answer to the number of interrupts in 8085 μP is indeed 5 (option B).
