Answer:
First I/O instruction format -> 256 ports
Second I/O instruction format -> 65536 ports
Explanation:
- For the first instruction format, we have eight bits for port addressing, therefore, the number of port addressed can be calculated as 2^8 = 256 ports
- For the second instruction format, we have sixteen bits for addressing, therefore, the number of ports addressed can be calculated as 2^16 = 65536 ports
The opcode selection allows us to change between the first and second instruction format, an opcode allows one input or output operation at a time.
