Question

TRAP is addressed by

• A. \(0016H\)
• B. \(0024H\)
• C. \(0033H\)
• D. \(0034H\)

Hint:

Remember: \[ TRAP \rightarrow 0024H \] It is non-maskable and has the highest priority in 8085.

Answer 1

The Correct Option is B

Concept:
TRAP is the highest-priority vectored interrupt in the 8085 microprocessor. Each vectored interrupt has a fixed interrupt service routine (ISR) address. & nbsp;

Step 1: Recall the interrupt vector addresses.
\[ \begin{array}{|c|c|} \hline \text{Interrupt} & \text{Vector Address} \\ \hline \text{TRAP} & 0024H \\ \text{RST 7.5} & 003CH \\ \text{RST 6.5} & 0034H \\ \text{RST 5.5} & 002CH \\ \hline \end{array} \]& nbsp;

Step 2: Identify the TRAP vector address.
From the table, \[ \boxed{\text{TRAP} = 0024H} \]& nbsp;

Answer: \[ \boxed{0024H} \]
