Question 297
|
Which interrupt in 8085 Microprocessor is unmaskable?
|
RST 5.5
|
|
|
RST 7.5
|
|
|
TRAP
|
|
|
Both (a) and (b)
|
Question 297 Explanation:
Interrupts are the signals generated by the external devices to request the microprocessor to perform a ask. There are 5 interrupt signals. Given low priority to high is
1. INTR
2. RST 5.5
3. RST 6.5
4. RST 7.5
5. TRAP
Maskable Interrupts: They can be enabled or disabled by software INTR,RST 5.5,RST 6.5 and RST 7.5
Un maskable Interrupts: TRAP
1. INTR
2. RST 5.5
3. RST 6.5
4. RST 7.5
5. TRAP
Maskable Interrupts: They can be enabled or disabled by software INTR,RST 5.5,RST 6.5 and RST 7.5
Un maskable Interrupts: TRAP
