long Whose result is more than 8 byte. The ?rst
number is stored from 7501 to 7508 and second
number is stored from 8501 to 8508 and result is
to be stored from 9501 to 8509.
6. ' Attempt any one part
' a) Explain the interrlipts sequence and types of
interrupts in 8086.
b) Draw explain the memory and 1/0 read cycle of
? 8085. ' '
7. Attempt any one part
a) Interface an 8255 with 8086 to work as an I/O pert.
Initialize port A as output port. Port B as input port
and port C as output port. The address of port A.
Port B, Port C and CWR is 0760, 0762, 0764 and
0766 a respectively. Write a programme to sense
switch positions ( 10110101) connected?at port B.
The sensed pattern is to be displayed on port A, to
which 8 LEDs are'connected, while port C lower
displays number of on switches out of the total eight
switches.
b) Discuss the mode of operation of 8253 programme,
internal times with its control format.
