Question
Download Solution PDFThe TRAP in 8085 is equivalent to __________ in 8086.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe TRAP interrupt in the 8085 microprocessor is most closely equivalent to the 3) NMI (Non-Maskable Interrupt) in the 8086 microprocessor.
Explanation:
- TRAP (8085):
- It is a non-maskable interrupt, meaning the programmer cannot disable it.
- It has the highest priority among all interrupts.
- It is typically used for critical events like power failures or hardware errors.
- NMI (8086):
- It is also a non-maskable interrupt.
- It also has a high priority, though not necessarily the absolute highest.
- It is used for similar critical events as the TRAP interrupt.
Here's why the other options are incorrect:
- RST 01 & RST 5 (8085):
- These are restart interrupts in the 8085, which are software interrupts or maskable hardware interrupts.
- INTR (8086):
- This is a maskable interrupt in the 8086, meaning it can be disabled.
Therefore, the closest equivalent to the TRAP interrupt in the 8085 is the NMI interrupt in the 8086.
