Which of the given signal has the highest priority?
Explanation: The Non-Maskable Interrupt input pin has the highest priority among all the external interrupts.
Which exception has highest priority in arm?
A normal return from the FIQ causes the Data Abort handler to resume execution. Data Aborts must have higher priority than FIQs to ensure that the transfer error does not escape detection….Exception priorities.
| Priority | Exception |
|---|---|
| Highest | Reset |
| Data Abort | |
| FIQ | |
| IRQ |
How interrupt is used in 8051?
Interrupts are the events that temporarily suspend the main program, pass the control to the external sources and execute their task. It then passes the control to the main program where it had left off. 8051 has 5 interrupt signals, i.e. INT0, TFO, INT1, TF1, RI/TI.
Which instruction can be used to assign INT1 highest priority?
Solution: The instruction “MOV IP, #0 0 0 0110 OB” (B is for binary) sets the external interrupt 1 (INT1) and Timer 1 (TF1) to a higher priority level compared with the rest of the interrupts.
Which register is used to select the register bank?
Register bank 0 is the default when the 8051 is powered up. We can switch to the other banks using PSW register. D4 and D3 bits of the PSW are used to select the desired register bank, since they can be accessed by the bit addressable instructions SETB and CLR.
What instruction performs Compare immediate to indirect and jump if not equal?
Short jump. Compares immediate data to indirect register and jumps if not equal.
What are the two types of instructions?
Types of Instruction
- Direct instruction. The Direct instruction strategy is highly teacher-directed and is among the most commonly used.
- Indirect instruction.
- Independent study.
- Interactive instruction.
- Experiential Learning.
What are the four different types of instructions?
The instruction types include load and store with reservation, synchronization, and enforce in-order execution of I/O. They are especially useful for multiprocessing. Flow Control Instructions – These include branch, Condition-Register logical, trap, and other instructions that affect the instruction flow.
