In an 8085 microprocessor based system the maximum possible number input/output devices can be connected using I/O mapped I/O technique is given by—
-
- 64
- 512
- 56
- 65536
Correct Option: B
In I/O mapped technique a maximum of 256 input devices and 256 output devices can be connected to the processor. Therefore, total number of I/O devices i.e., 256 + 256 = 512 can be connected using I/O mapped I/O techniques.
