S1: Separate I/O address space does not necessarily mean that I/O address lines are physically separated from the memory address lines. A special signal on the bus indicates that the requested read or write transfer is an I/O operation.
S2: The address decoder, the data and status register, and control circuitry required to coordinate I/O transfers constitute the interface circuit (Hence true).

The false statement in the given options is:
S1: Separate I/O address space does not necessarily mean that I/O address lines are physically separated.
This statement is false because separate I/O address space does mean that I/O address lines are physically separated. Separate I/O address space refers to having a distinct address range for I/O devices, different from the address range used for memory. The physical separation of I/O address lines ensures that there is no conflict between memory and I/O operations. If the I/O address lines are not physically separated, it can lead to interference or conflicts between memory and I/O devices.
S2: Address decoder is an essential part of I/O interface.
This statement is true. An address decoder is an essential part of the I/O interface. It is responsible for decoding the address lines received from the CPU and selecting the appropriate I/O device based on the decoded address. The address decoder consists of logic gates that compare the received address with the assigned addresses of the I/O devices. It generates the necessary control signals to enable the selected I/O device and initiate the data transfer.
Explanation:
The I/O interface is responsible for facilitating communication between the CPU and the I/O devices. It consists of various components, including address lines, data lines, control lines, and an address decoder.
Separate I/O address space refers to having a distinct address range for I/O devices. This ensures that the CPU can distinguish between memory and I/O operations. The I/O address lines are physically separated to avoid conflicts or interference between memory and I/O devices.
The address decoder is an essential part of the I/O interface. It decodes the address lines received from the CPU and selects the appropriate I/O device based on the decoded address. The address decoder compares the received address with the assigned addresses of the I/O devices and generates the necessary control signals to enable the selected I/O device and initiate the data transfer.
Therefore, the false statement is S1: Separate I/O address space does not necessarily mean that I/O address lines are physically separated.
