(a)What are the advantages and disadvantages of I/O mapped I/O over memory mapped I/O?

Explain why I/O mapped I/O data transfer technique is limited to 256 input and 256 output

peripherals.

(b) What do you mean by priority interrupts? Explain the operation of different interrupts available

in 8085, with the help of circuit diagram.

 (c)Draw an interface circuit of a D/A converter with 8085μP and write a program to convert the

digital input to analog output.
