Question 9

The 8085 microprocessor responds to the present of an interrupt

A
as soon as the TRAP pin becomes ‘high’
B
by checking the TRAP pin for ‘high’ status at the end of each instruction each
C
by checking the TRAP pin for ‘high’ status at the end of the execution of each instruction
D
by checking the TRAP pin for ‘high’ status at regular intervals
Question 9 Explanation: 
TRAP is non maskable interrupt . TRAP is active high, level, edge triggered non maskable highest priority interrupt. When TRAP line is active microprocessor insert intervals restarts automatically at vector location of TRAP.
